CVE-2023-32350: Versions 00.07.00 through 00.07.03 of Teltonika’s RUT router firmware contain an operating system (OS) command injection vulnerability in a

Noroxi assessment

Priority: Monitor (action score 35/100)

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: 1.5% (FIRST EPSS); higher than 74.4% of all records.
Anyone who can reach it over the internet 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.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

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

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

Versions 00.07.00 through 00.07.03 of Teltonika’s RUT router firmware contain an operating system (OS) command injection vulnerability in a Lua service. An attacker could exploit a parameter in the vulnerable function that calls a user-provided package name by instead providing a package with a malicious name that contains an OS command injection payload.
