CVE-2025-14558: Remote code execution via ND6 Router Advertisements
Noroxi assessment
Priority: Plan (action score 40/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Because a ready-made attack tool exists, priority is at least “Plan”.
- Probability of exploitation in the next 30 days: 6.5% (FIRST EPSS); higher than 93.7% of all records.
- Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: FreeBSD FreeBSD p1, p7, p8.
Add it to your regular patch cycle. Upgrade to FreeBSD FreeBSD p1, p7, p8 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf(8) unmodified. resolvconf(8) is a shell script which does not validate its input. A lack of quoting meant that shell commands pass as input to resolvconf(8) may be executed.
