**Name of the Vulnerable Software and Affected Versions** TBK DVR4104 and DVR4216 devices, as well as Novo, CeNova, QSee, Pulnix, XVR 5 in 1, Securus, Night OWL, DVR Login, HVR Login, and MDVR Login **Description** The issue allows remote attackers to bypass authentication via a "Cookie: uid=admin" header. This can be demonstrated by a device.rsp?opt=user&cmd=list request that provides credentials within JSON data in a response. Exploitation of this issue may allow a remote attacker to bypass security restrictions and gain unauthorized access to protected information by sending a specially crafted request. There has been a spike in attacks against TBK DVR devices. **Recommendations** For TBK DVR4104 and DVR4216 devices, as well as Novo, CeNova, QSee, Pulnix, XVR 5 in 1, Securus, Night OWL, DVR Login, HVR Login, and MDVR Login, consider disabling the `uid=admin` header in the Cookie to prevent authentication bypass until a patch is available. As a temporary workaround, restrict access to the device.rsp?opt=user&cmd=list endpoint to minimize the risk of exploitation. Avoid using the `uid` variable in the Cookie header in the affected devices until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Anti-Web through version 3.8.7 **Description** The issue allows remote authenticated users to execute arbitrary OS commands via crafted `multipart/form-data` content. This affects devices from various manufacturers, including NetBiter / HMS, Ouman EH-net, Alliance System WS100 --> AWU 500, Sauter ERW100F001, Carlo Gavazzi SIU-DLG, AEDILIS SMART-1, SYXTHSENSE WebBiter, ABB SREA, and ASCON DY WebServer. **Recommendations** For Anti-Web version 3.8.7 and earlier, consider restricting access to the `cgi-bin/write.cgi` endpoint to minimize the risk of exploitation. As a temporary workaround, avoid using the `multipart/form-data` content type in the affected endpoint until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
