Summary

CVE-2025-13305 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Dir-825M Firmware. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 12% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-13305 is a buffer overflow vulnerability (CWE-119, CWE-120) identified in D-Link routers, specifically models DWR-M920, DWR-M921, DWR-M960, DIR-822K, and DIR-825M running firmware version 1.01.07. The flaw affects the processing of the /boafrm/formTracerouteDiagnosticRun file, where manipulation of the "host" argument triggers the buffer overflow. Published on 2025-11-17, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity.

The vulnerability enables remote exploitation by attackers with low privileges over the network, requiring no user interaction and low attack complexity. Successful exploitation of the buffer overflow can result in high impacts to confidentiality, integrity, and availability, potentially allowing arbitrary code execution or system compromise on the affected device.

References point to VulDB entries (ctiid.332645, id.332645, submit.691809, submit.691816) and a GitHub issue (LX-LX88/cve/issues/12) for further details, but no official vendor advisories or patches are specified in the available information.

An exploit for this vulnerability has been publicly disclosed, heightening the potential for real-world attacks against unpatched devices.
