CVE-2026-92838 affects GeoVision GV-Remote E-Map through unsafe DLL loading. The 7.8 CVSS score places this issue in the high-severity range, but the practical attack path is constrained by the local-access requirement. An attacker must be able to write a malicious DLL into a directory searched by the application before the legitimate library location.
The patch status requires particular caution. The available NVD material identifies the product and vulnerability class but does not publish an affected version range or fixed version. Administrators should therefore treat all installed GV-Remote E-Map versions as potentially exposed until GeoVision provides version-specific guidance.
What Is This Vulnerability?
CVE-2026-92838 is caused by unsafe DLL loading in the Windows desktop application. When GV-Remote E-Map requests a dynamic-link library, the application or its execution environment searches locations in an order that can allow an attacker-controlled file to be selected before the intended legitimate library.
The exploitation sequence is straightforward. A local attacker places a malicious DLL with the expected filename in a writable directory included in the search path. When GV-Remote E-Map starts or reaches the affected code path, Windows loads the malicious library. Code in that DLL then executes with the permissions of the GV-Remote E-Map process.
This is not described as a remotely reachable network vulnerability. The attacker needs local access to the Windows system and write access to an appropriate searched directory. The resulting code execution can nevertheless be consequential on systems where the application runs with elevated permissions or where the workstation has access to video management infrastructure, credentials, administrative tools, or sensitive network segments.
The available record does not identify the specific DLL name, triggering application function, or exact search-path directory. Defenders should avoid assuming that a particular filename or directory is authoritative unless it is confirmed through vendor documentation, controlled testing, or endpoint telemetry.
Who Is Affected?
The identified affected product is GeoVision GV-Remote E-Map, a Windows desktop application. The retrieved CVE information does not specify whether the issue affects a particular major release, installer generation, architecture, or update branch.
| Product | Affected version range | Fixed version | Current assessment |
|---|---|---|---|
| GeoVision GV-Remote E-Map | Not specified in the available CVE record | Not identified | Requires GeoVision confirmation |
Organizations should inventory both actively used and dormant installations. A workstation may remain exposed even if operators rarely launch the application, because a malicious DLL can execute the next time the program starts. Include engineering workstations, security operations consoles, guard stations, remote-support systems, and systems where the application was installed for testing.
The absence of a published version range does not establish that only a single release is affected. Until GeoVision identifies affected and fixed versions, use the installed-version inventory as the basis for risk decisions and prioritize systems with broad network access, local administrator users, shared writable directories, or weak application-control coverage.
A basic PowerShell inventory check can locate common installation directories, although the path is not confirmed as authoritative for this CVE:
$roots = @(
"$env:ProgramFiles\GeoVision",
"${env:ProgramFiles(x86)}\GeoVision",
"$env:ProgramData\GeoVision"
)
$roots | Where-Object { Test-Path $_ } |
ForEach-Object {
Get-ChildItem -Path $_ -Recurse -File -ErrorAction SilentlyContinue |
Where-Object { $_.Name -match 'GV-Remote|E-Map' } |
Select-Object FullName, Length, LastWriteTime,
@{Name='ProductVersion';Expression={$_.VersionInfo.ProductVersion}}
}
CVSS Score Breakdown
NVD assigns CVE-2026-92838 a CVSS base score of 7.8. The retrieved NVD result does not include the CVSS vector string, so the individual metric values cannot be stated reliably. In particular, the available score alone does not prove the values for attack complexity, privileges required, user interaction, scope, or the confidentiality, integrity, and availability impact metrics.
The vulnerability description supports a local attack vector because exploitation requires access to the Windows system and write access to a searched directory. It also supports arbitrary code execution as the impact. However, local access should not automatically be translated into a formal CVSS privileges-required value, and the record does not establish whether exploitation requires a victim to launch the application or whether any other interaction is necessary.
For prioritization, organizations should use the 7.8 score together with environmental factors. A system running GV-Remote E-Map under a highly privileged account, located in a security-management network, or allowing many users to write to application-adjacent directories presents greater operational risk than an isolated workstation with restrictive ACLs. The missing vector is a documentation gap that should be resolved through the NVD record update or GeoVision advisory.
Exploitation Status
CVE-2026-92838 was not listed in the CISA Known Exploited Vulnerabilities catalog as of the 17 September 2026 assessment date. No CISA confirmation of exploitation, KEV due date, required action, or ransomware-campaign association exists for this CVE in the checked catalog.
No verified CVE-specific public proof-of-concept repository was identified in the reviewed material, and confirmed exploitation in the wild was not established. The available references include a HackerOne report about DLL hijacking in Monero for Windows and a CVE.org link for CVE-2020-26947. Neither reference is a proof of concept for GeoVision GV-Remote E-Map, and they should not be used as evidence that this CVE has been exploited.
The absence of a KEV listing or public PoC does not prove that exploitation has never occurred. DLL hijacking is a well-known Windows execution technique, and attackers may use private tooling. Treat the status as no confirmed exploitation identified, not as evidence of zero risk.
How to Detect It
Detection should focus on GV-Remote E-Map loading a DLL from a user-writable or otherwise unexpected directory. Useful telemetry includes Sysmon Event ID 7, which records image and DLL loads when image-load monitoring is enabled, as well as process-creation events, file-creation events, and endpoint security alerts involving the GeoVision application.
Security teams can also incorporate these alerts into a broader threat hunting workflow and correlate application launches with file writes, privilege changes, and suspicious parent processes. Because the vulnerable DLL name and exact search path are not published, detection rules should begin with the application process rather than a presumed library filename.
A generic Splunk-style query for Sysmon image-load events is:
index=endpoint sourcetype=XmlWinEventLog:Microsoft-Windows-Sysmon/Operational
EventCode=7
ImageLoaded="*GV-Remote*"
| eval dll_path=lower(ImageLoaded)
| where like(dll_path, "c:\\users\\%")
OR like(dll_path, "c:\\programdata\\%")
OR like(dll_path, "c:\\temp\\%")
OR like(dll_path, "%\\downloads\\%")
| table _time, Computer, Image, ImageLoaded, Signed, Signature, User
Adapt the process and field names to the EDR platform. Investigate any unsigned or unexpectedly signed DLL loaded by the application, particularly when the DLL originates from a profile directory, temporary directory, network share, or application directory with non-administrative write permissions.
File-integrity monitoring can add context. Record new DLL creation or modification events beneath GeoVision installation directories and compare the file owner, signer, hash, and timestamp with known-good software. Also review process ancestry: an unusual GV-Remote E-Map launch from a script, archive extraction utility, document viewer, remote-management tool, or temporary directory may indicate staging activity.
Mitigation and Patching
No specific affected version range or fixed version was identified in the reviewed NVD and vendor-reference material. Consequently, there is no defensible version number to cite as the required upgrade target. Administrators should obtain the current GeoVision release directly from the vendor and verify that its release notes or security advisory explicitly addresses CVE-2026-92838 before declaring the issue remediated.
Until a verified fix is available, restrict write access to directories that could be searched for application DLLs. Do not run GV-Remote E-Map from a user-writable directory, and avoid granting standard users modify permissions on the application installation tree. These controls reduce the likelihood of DLL planting but may not eliminate every unsafe search-path condition.
For an installation located at a confirmed path, administrators can remove inherited modification rights for standard users and grant read and execute access instead. Test this first because changing ACLs can affect product updates and support workflows:
$path = 'C:\Program Files\GeoVision\GV-Remote E-Map'
icacls $path /inheritance:r
icacls $path /grant:r 'SYSTEM:(OI)(CI)(F)' 'Administrators:(OI)(CI)(F)' 'Users:(OI)(CI)(RX)'
icacls $path /remove:g 'Authenticated Users'
The example must be adapted to the organization’s actual installation path and local security model. Do not apply it blindly to a directory used by an updater that requires standard-user write access. If the application is installed under a user profile, move or reinstall it into an administrator-controlled location when supported by GeoVision.
Additional interim controls include application allowlisting, Windows Defender Application Control or AppLocker policies, endpoint rules that block unsigned DLLs from user-writable paths, and least-privilege execution for the application. Enable appropriate Windows and EDR telemetry, then monitor for anomalous DLL loads while awaiting vendor confirmation.
If investigation identifies exposed credentials on an affected workstation, rotate them through the organization’s approved process and store replacement credentials in an enterprise password manager such as Try 1Password →. This is a supporting control, not a substitute for patching, ACL hardening, or application allowlisting.
Once GeoVision publishes a fixed version, test it and deploy it through the organization’s normal software-distribution process, recording the exact installed version and validation evidence. Security teams can also route detections and remediation tasks through a security orchestration workflow, such as the process described in security orchestration and SOAR.
