**Name of the Vulnerable Software and Affected Versions** ASUS GT-AC2900 versions prior to 3.0.0.4.386.42643 Lyra Mini versions prior to 3.0.0.4 384 46630 **Description** The administrator application on ASUS GT-AC2900 and Lyra Mini devices allows authentication bypass when processing remote input from an unauthenticated user, leading to unauthorized access to the administrator interface. This issue relates to the `handle request` function in `router/httpd/httpd.c` and `auth check` in `web hook.o`. An attacker-supplied value of `0` matches the device's default value of `0` in some situations. There have been attempts to exploit this issue, with 379,868 attempts reported as failed due to a tiny error. **Recommendations** For ASUS GT-AC2900 versions prior to 3.0.0.4.386.42643, update to version 3.0.0.4.386.42643 or later. For Lyra Mini versions prior to 3.0.0.4 384 46630, update to version 3.0.0.4 384 46630 or later. As a temporary workaround, consider disabling the remote access features from WAN to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Lenovo Accelerator Application (affected versions not specified) **Description** The issue allows man-in-the-middle attackers to execute arbitrary code by spoofing an update response from the `susapi.lenovomm.com` API endpoint. This is due to a flaw in the UpdateAgent component. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
