CVE-2025-70329: TOTOLink X5000R v9.1.0cu_2415_B20250515 contains an OS command injection vulnerability in the setIptvCfg handler of the /usr/sbin/lighttpd e

Noroxi assessment

Priority: Monitor (action score 33/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.4% (FIRST EPSS); higher than 88.9% of all records.
  • Someone on the same network segment can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

TOTOLink X5000R v9.1.0cu_2415_B20250515 contains an OS command injection vulnerability in the setIptvCfg handler of the /usr/sbin/lighttpd executable. The vlanVidLan1 (and other vlanVidLanX) parameters are retrieved via Uci_Get_Str and passed to the CsteSystem function without adequate validation or filtering. This allows an authenticated attacker to execute arbitrary shell commands with root privileges by injecting shell metacharacters into the affected parameters.
