利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
以下漏洞描述信息的中文翻译： --- 若干管理操作未充分验证请求是否由已认证用户有意发起。特别是， 操作可通过 GET 请求触发，而无需验证 ChallengeToken。因此，远程未认证攻击者可以通过在恶意网页中嵌入构造好的请求，促使已认证管理员的浏览器执行该清理操作。成功利用此漏洞可能导致删除现有的 DBUpdate 日志条目，从而降低用于故障排除和审计的诊断及历史信息可用性。其影响仅限于在伪造请求处理时已存在的 DBUpdate 日志条目。 此外，还发现了其他若干未验证 ChallengeToken 的管理端

Vulnerability Title
Cross-Site Request Forgery in Administrative Actions
来源: CVE Program / CVE List V5
Vulnerability Description
Several administrative actions do not sufficiently validate whether a request was intentionally initiated by the authenticated user. In particular, the DBUpdateLogCleanUp action can be triggered through a GET request without validating a ChallengeToken. An unauthenticated remote attacker can therefore cause the browser of an authenticated administrator to execute the cleanup action by embedding a crafted request in a malicious web page. Successful exploitation can delete existing DBUpdate log entries. This may reduce the availability of diagnostic and historical information used for troubleshooting and auditing. The impact is limited to DBUpdate log entries that exist at the time the forged request is processed.
Additional administrative endpoints were identified that do not validate a ChallengeToken. Some of these endpoints can trigger administrative actions such as deploying or synchronizing already existing configuration. They do not allow an attacker to introduce arbitrary new configuration through the CSRF request itself.
Export and read-only endpoints were also identified without ChallengeToken validation. While these endpoints may be triggered through a forged cross-site request, the response content remains subject to the browser's same-origin restrictions and is not automatically exposed to the attacker. Therefore, no direct confidentiality impact has been demonstrated for these endpoints.
This issue affects OTRS:
* 7.0.X
* 8.0.X
* 2023.X
* 2024.X
* 2025.X
* 2026.X before 2026.7.X
Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected
