1DescriptionCVE.org
A weakness has been identified in Yot CMS up to 3.3.1. Affected by this vulnerability is the function Login of the file global.php of the component Cookie Handler. This manipulation of the argument yot3_user/yot3_pass causes sql injection. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks.
AnalysisAI
SQL injection in Yot CMS 3.3.x via the Login function in global.php allows remote unauthenticated attackers to supply crafted SQL payloads through the yot3_user and yot3_pass cookie values, bypassing authentication and forging administrator sessions. The researcher-published GitHub PoC (by dddwmr) explicitly demonstrates full admin session forgery as the end result, making the assigned CVSS 5.5 score a material understatement of actual impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the Yot CMS cookie-based auto-login feature to be active, which is the default behavior of the Login function in global.php processing yot3_user and yot3_pass cookies on each request. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.5 with impact metrics VC:L/VI:L/VA:L appears to significantly understate actual risk: the PoC documentation title explicitly states the vulnerability 'enables forged administrator sessions,' which corresponds to C:H/I:H rather than the low ratings assigned by the reporter. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch or fixed version for Yot CMS has been identified at time of analysis - no advisory or tagged release was referenced in the input. … Detailed patch versions, workarounds, and compensating controls in full report. |
