CVE-2025-14558
CVE-2025-14558 FreeBSD rtsold DNSSL Command Injection RCE Description rtsold8 does not validate DNSSL domain names for shell metacharacters before passing them to resolvconf8. Command substitution via $ enables remote code execution from an adjacent network. Affected: FreeBSD 13.x, 14.x, 15.x...
Blackash-CVE-2025-14558
đš CVE-2025-14558 : Critical Remote Code Execution in FreeBSD IPv6 đ§ Overview CVE-2025-14558 is a critical Remote Code Execution RCE vulnerability affecting FreeBSD systems that use IPv6 router solicitation services. A flaw in how untrusted network input is handled allows attackers to execute...
đ FreeBSD rtsold/rtsol DNSSL Command Injection
This Metasploit module exploits a command injection vulnerability CVE-2025-14558 in FreeBSD's rtsol8 and rtsold8 programs. These programs do not validate the domain search list options provided in IPv6 Router Advertisement messages; the option body is passed to resolvconf8 unmodified. resolvconf8...
đ FreeBSD 15.x rtsold DNSSL Command Injection
This Metasploit module targets a command injection vulnerability in the FreeBSD rtsold daemon related to the handling of DNSSL DNS Search List options in IPv6 Router Advertisements. Due to improper validation of domain names, attacker-controlled DNSSL values can inject shell commands via $...
đ FreeBSD rtsold 15.x Remote Code Execution
rtsold8 on FreeBSD processes IPv6 Router Advertisement DNSSL options without validating domain names for shell metacharacters. The decoded domains are passed to resolvconf8, a shell script that uses unquoted variable expansion, enabling command injection via substitution. Exploit Title: FreeBSD...

PT-2025-51802
Name of the Vulnerable Software and Affected Versions FreeBSD affected versions not specified Description A remote code execution issue exists in the IPv6 autoconfiguration handler in FreeBSD. The issue is present in the rtsold background process and the rtsol utility. An attacker can achieve...
FreeBSD -- Remote code execution via ND6 Router Advertisements
Problem Description: The rtsol8 and rtsold8 programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf8 unmodified. resolvconf8 is a shell script which does not validate its input. A lack of quoting meant that shell...

CVE-2020-25583
CVE-2020-25583 affects FreeBSD rtsold(8) handling of DNSSL and RDNSS options. The issue arises from insufficient bounds checking and incorrect validation of label lengths when decoding domain name labels (RFC 1035 encoding) in the DNSSL option, which could overflow the destination buffer. Affecte...
CVE-2020-25577
CVE-2020-25577 affects FreeBSD rtsold: insufficient bounds checking on RDNSS option extent (and related DNSSL handling) can allow malformed Router Advertisement data to flow to userspace, potentially enabling remote code execution in rtsold(8). Affects multiple FreeBSD branches (stable/11, stable...
