Detailsinfo

A vulnerability has been found in Schweitzer Engineering Laboratories SEL-3350-1, SEL-3355-2 and SEL-3360-2 and classified as problematic. Affected by this vulnerability is an unknown part of the component BIOS Setting Handler. The manipulation with an unknown input leads to a authentication bypass vulnerability. The CWE definition for the vulnerability is CWE-305. The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error. As an impact it is known to affect integrity. The summary by CVE is:

SEL BIOS packages prior to 1.3.49152.117 or 2.6.49152.98 allow a local attacker to bypass password authentication and change password-protected BIOS settings by importing a BIOS settings file with no password set.

The advisory is shared at selinc.com. This vulnerability is known as CVE-2025-46750 since 04/28/2025. The exploitation appears to be easy. An attack has to be approached locally. Additional levels of successful authentication are necessary for exploitation. Neither technical details nor an exploit are publicly available.
