D-Link DIR-825 miniupnpd upnpsoap.c AddPortMapping buffer overflow
Noroxi assessment
Priority: Monitor (action score 29/100)
- 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: 0.74% (FIRST EPSS); higher than 54.3% 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.
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
A security flaw has been discovered in D-Link DIR-825 up to 3.00b32. This impacts the function AddPortMapping of the file upnpsoap.c of the component miniupnpd. Performing a manipulation of the argument NewPortMappingDescription results in buffer overflow. The attack needs to be approached within the local network. The exploit has been released to the public and may be used for attacks. This vulnerability only affects products that are no longer supported by the maintainer.
