PatchTheCVECVE-2025-41755: A low-privileged remote attacker can exploit the ubr-logread method in wwwubr.cgi to read arbitrary files on t
CVE-2025-41755 is a medium-severity flaw (CVSS 6.5) affecting universal bacnet router firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A low-privileged remote attacker can exploit the ubr-logread method in wwwubr.cgi to read arbitrary files on the system. The endpoint accepts a parameter specifying the log file to open (e.g., /tmp/weblog{some_number}), but this parameter is not properly validated, allowing an attacker to modify it to reference any file and retrieve its contents.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
