CVE-2026-48248: Improper Certificate Validation in Open ISES Tickets
Open ISES Tickets before 3.44.2 disables TLS certificate verification in incs/login.inc.php by setting CURLOPT_SSL_VERIFYPEER to false (and not setting CURLOPT_SSL_VERIFYHOST) when issuing outbound HTTPS requests issued during the login/authentication flow. An attacker positioned on the network path between the server and the remote endpoint can present a forged certificate to intercept, monitor, or modify the request and response, including any API keys or session-bearing data in transit.
AI Analysis
Technical Summary
The vulnerability in Open ISES Tickets prior to version 3.44.2 involves disabled TLS certificate verification in the incs/login.inc.php file. Specifically, the cURL options CURLOPT_SSL_VERIFYPEER is set to false and CURLOPT_SSL_VERIFYHOST is not set when making outbound HTTPS requests during login and authentication. This misconfiguration enables a man-in-the-middle attacker to present a forged TLS certificate, intercepting or altering sensitive data in transit, such as API keys and session information. The CVSS 4.0 base score is 8.2, indicating a high severity vulnerability with network attack vector, high complexity, and no privileges or user interaction required.
Potential Impact
An attacker positioned on the network path can exploit this vulnerability to intercept, monitor, or modify HTTPS requests and responses during the login/authentication process. This could lead to exposure or theft of API keys, session tokens, or other sensitive data transmitted in these requests, potentially compromising user accounts or system integrity.
Mitigation Recommendations
No official fix or patch is currently confirmed for this vulnerability. Users of Open ISES Tickets should upgrade to version 3.44.2 or later once available, as this version presumably corrects the improper certificate validation. Until then, users should consider mitigating the risk by restricting network access to trusted endpoints or using additional network-layer protections. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
