CVE-2026-13695: Integratec SQL Injection

Are You Affected?

CVE-2026-13695 affects the Integratec application, specifically the login-related endpoint /login/ap_Login.aspx/start. The vulnerable parameter is sInfo, supplied in a POST request. Available NVD and INCIBE material identifies the product and component but does not publish a reliable affected-version range or corrected version.

Organizations operating Integratec should inventory every deployment, including internally hosted, partner-hosted, and internet-facing installations. The endpoint alone does not establish a vulnerable version, but it is a strong scoping indicator because the advisory identifies that route and parameter as the attack surface.

An installation is not necessarily safe because it sits behind a VPN or because the login page is not indexed. An attacker who reaches the application through a compromised account, exposed administrative network, reverse proxy, or adjacent system may still be able to submit crafted requests.

For broader guidance on reducing exposure for internally hosted applications, see this practical checklist for secure self-hosted services.

The Fix, If You’re in a Hurry

No fixed version number is identified in the retrieved NVD record or INCIBE advisory material. Obtain the vendor’s corrected release and upgrade instructions directly from Integratec or the supplier responsible for the deployment. Do not substitute an assumed version number or treat a routine application update as confirmation that this vulnerability is fixed.

Until the vendor confirms remediation, reduce exposure to the affected endpoint. If business requirements permit, restrict /login/ap_Login.aspx/start to trusted source networks, place it behind an authenticated reverse proxy or VPN, and apply request filtering at the web application firewall. These controls reduce exposure but do not repair the SQL injection.

If the incident review finds exposed or reused credentials, reset them through your normal identity process and consider a business-approved password manager such as Try 1Password →. Password hygiene can limit follow-on risk, but it does not remediate the vulnerable application or database query.

Technical Notes

A temporary web-server rule can block direct access while the vendor response is pending. The exact syntax depends on the reverse proxy; the following NGINX example is a restrictive placeholder that must be tested against the application’s legitimate login flow:

location = /login/ap_Login.aspx/start {
    allow 10.0.0.0/8;
    allow 172.16.0.0/12;
    allow 192.168.0.0/16;
    deny all;
}

The network ranges above are examples, not a universal safe policy. Replace them with the actual administrator or application-client networks. Do not rely on simple keyword blocking for UNION, quotes, or SQL comments as the primary workaround because encoding, alternate syntax, and false positives can bypass or disrupt such filters.

After receiving a vendor-approved release, document the installed version before and after the change. For an IIS-hosted deployment, identify the application package or deployment method rather than assume a universal command. A generic operational workflow is:

# Record the current deployment state; adapt the path to your installation.
Get-ChildItem "C:\inetpub\wwwroot\Integratec" -Recurse -File |
  Select-Object FullName, LastWriteTime, Length

# Stop the site only during the vendor-approved maintenance window.
Stop-Website -Name "Integratec"

# Apply the vendor-supplied update using its documented installer or package command.
# Do not invent package names or version switches:
# <vendor-approved-installer> /quiet

Start-Website -Name "Integratec"

How This Vulnerability Works

The issue is described as UNION-based SQL injection in the sInfo parameter. In a vulnerable implementation, attacker-controlled input may be incorporated into a database query without sufficient parameterization or validation. A UNION-based attack attempts to append or combine a second query with the application’s original query so that database-controlled results are returned through the application response.

The login endpoint is particularly sensitive because database queries in authentication workflows may process usernames, account metadata, session information, or other identity-related records. If the database account used by the application has excessive privileges, exploitation could expose credentials, user information, or additional database tables. The advisory also describes application errors and partial denial-of-service conditions.

Available material does not identify the database engine, exact vulnerable query, required payload structure, database account privileges, or precise response behavior. Defenders should not infer those details from the CVSS score. Unexpected database errors, abnormal response sizes, and requests containing SQL control syntax are investigation leads, not proof of exploitation.

Severity, Explained

NVD reports a CVSS base score of 8.8, rated High. The retrieved record does not include the CVSS vector string, so the individual metric values, including the exact network, authentication, confidentiality, integrity, and availability components, cannot be reliably enumerated.

The score indicates substantial potential impact, but it does not establish that every deployment is internet-accessible or that exploitation has been confirmed. Risk is higher when the endpoint is exposed to untrusted networks, the application’s database identity can read sensitive tables, credentials are stored insecurely, or the Integratec instance contains privileged user records.

The reported impact includes database disclosure, credential and user-information theft, application errors, partial denial of service, and possible follow-on activity such as data exfiltration or privilege escalation. Conduct an environment-specific assessment using exposure, database permissions, data sensitivity, and compensating controls.

Analyst’s Take: The missing affected-version range and fixed release make vendor confirmation the first remediation dependency. Until that information is available, endpoint restriction and retrospective log review are the most concrete actions because they reduce exposure and may identify prior suspicious activity without assuming that exploitation has occurred.

Is It Being Exploited?

No confirmed in-the-wild exploitation was identified in the retrieved sources. CVE-2026-13695 is also not listed in the CISA Known Exploited Vulnerabilities catalog as of the publication date in this assessment. There is no CISA KEV confirmation or KEV remediation deadline for this CVE at the time of checking.

No public proof-of-concept repository or exploit reference was identified in the retrieved NVD record or supplied advisory material. This status can change after publication, and the absence of a public PoC does not make a remotely reachable SQL injection safe. Attackers can develop private exploit code from advisory details or discover the issue independently.

Organizations should avoid both extremes. There is no current evidence requiring a claim of active exploitation, but the vulnerability still warrants priority handling because it affects a login endpoint and may expose database content. Preserve relevant logs before making configuration changes and investigate activity retrospectively.
