6DescriptionCVE.org
A security vulnerability has been detected in halex CourseSEL up to 1.1.0. Affected by this vulnerability is the function check_sel of the file Apps/Index/Controller/IndexController.class.php of the component HTTP GET Parameter Handler. The manipulation of the argument seid leads to sql injection. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
SQL injection in halex CourseSEL up to version 1.1.0 allows authenticated remote attackers to execute arbitrary SQL queries via the seid parameter in the HTTP GET request handler, potentially leading to unauthorized data access, modification, and denial of service. The vulnerability affects the check_sel function in IndexController.class.php and has publicly available exploit code; the vendor has not responded to early disclosure notifications.

Vulnerability AssessmentAI
| Risk Assessment | The CVSS v3.1 score of 6.3 reflects a medium-severity vulnerability with network-accessible attack vector and low attack complexity, but requires low-level user privileges (PR:L) and causes limited confidentiality, integrity, and availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated user with valid credentials to halex CourseSEL crafts a malicious GET request to the IndexController's check_sel function, injecting SQL syntax into the seid parameter (e.g., seid=1' OR '1'='1). The vulnerable application concatenates this unsanitized input directly into an SQL query, allowing the attacker to extract sensitive course data, modify grades or course content, or disable course availability. … |
| Remediation | Immediate remediation requires upgrading to a patched version of halex CourseSEL; however, no vendor-released patched version is confirmed at this time due to vendor non-responsiveness to disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
