This affects the function checkSysPwd of the file com/ahsay/obs/api/ApiStructsAction.java of the component API. Performing a manipulation of the argument random results in improper authentication. It is possible to initiate the attack remotely. The exploit is now public and may be used. Upgrading to version 9.15.2.70 and 10.3.4.45 is able to mitigate this issue. It is recommended to upgrade the affected component. The initial patch did not fix the security vulnerability properly. An update of the CVE entry to reflect this became necessary.","cwes":["CWE-287"],"vendors":[{"vendor":"cloudflare","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"aws","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"azure","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"google","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"fastly","status":"no_history","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"f5","status":"rule","basis":"claimed","firstOn":"2026-10-21","firstIsNew":true,"daysToRule":17,"daysAtMost":null,"freePlan":false,"claims":[{"id":"c96565aa1535050d076bb5d56b88c2a64c64b7da301e03b637ba9c2e3aba0250","cve_id":"CVE-2026-105133","vendor":"f5","product":"Attack signatures","rule_id":"200013237","rule_name":"AhsayCBS Authentication Bypass","change":"new","default_action":null,"published_on":"2026-10-21","source_url":"https://docs.cloud.f5.com/docs-v2/platform/changelogs/security-details-changelog","source_title":"F5 Distributed Cloud attack signatures changelog","excerpt":"Added: signature 200013237 \"AhsayCBS Authentication Bypass\" (Authentication/Authorization Attacks, risk High), systems: Other Web Server.
