Noroxi assessment

Priority: Plan (action score 41/100)

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: 6.9% (FIRST EPSS); higher than 94.1% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

D-Link DIR-868L B1 router firmware version FW2.05WWB02 contains an unauthenticated OS command injection vulnerability in the fileaccess.cgi component. The endpoint /dws/api/UploadFile accepts a pre_api_arg parameter that is passed directly to system-level shell execution functions without sanitization or authentication. Remote attackers can exploit this to execute arbitrary commands as root via crafted HTTP requests.
