Questions about CVE-2023-25280
What does this mean?
A crafted payload sent through the ping_addr parameter can inject operating system commands, which lets an attacker raise privileges to root.Source: github.com
Am I affected, and how do I check?
The checked facts name firmware DIR820LA1_FW105B03 with the ping.ccp component. The vulnerable code is reached when the ccp_act parameter is set to pingV4Msg. To check a device, compare its firmware version against DIR820LA1_FW105B03 in the admin interface.Source: github.com
What should I do about it?
The checked facts give no fixed version, so no upgrade target can be named. Check the vendor's site for a firmware release that addresses this issue.Source: github.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-09-30, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
The checked facts give no workaround. The vulnerable path runs through the pingV4Msg action of ping.ccp, so limiting use of that ping feature is the only option the facts point to.Source: github.com
