DSR-150: Path Traversal: '../filedir'
CVE-2025-60344 is a high-severity path traversal: '../filedir' vulnerability in DSR-150 from D-Link, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected DSR-150 versions: 1.09B32_WW. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 11.4% chance of exploitation within 30 days, which is in the top 3.93% of all scored CVEs.
EPSS places it among the vulnerabilities most likely to be exploited soon.
What to do
- Check which version of DSR-150 you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A path traversal (directory traversal) vulnerability in D-Link DSR series routers allows unauthenticated remote attackers to manipulate input parameters used for file or directory path resolution (e.g., via sequences such as “../”). Successful exploitation may allow access to files outside of the intended directory, potentially exposing sensitive system or configuration files. The issue results from insufficient validation or sanitization of user-supplied input. Affected Products include: DSR-150, DSR-150N, and DSR-250N v1.09B32_WW.

The underlying weakness: Path Traversal: '../filedir'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize../ sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
