Published: 06 May 2025
Summary
CVE-2025-4354 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Dap-1520 Firmware. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 19.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A vulnerability identified as CVE-2025-4354 exists in the Tenda DAP-1520 wireless access point running firmware version 1.10B04_BETA02. The issue resides in the check_dws_cookie function of the /storage component, where improper handling of input allows a stack-based buffer overflow. The flaw is tracked under CWE-119, CWE-121, and CWE-787 and carries a CVSS 4.0 score of 8.7.
An authenticated remote attacker can send crafted requests to the affected device to trigger the overflow. Successful exploitation grants the ability to corrupt memory and achieve high impact on confidentiality, integrity, and availability without requiring user interaction. A proof-of-concept has already been published, confirming that the attack can be launched over the network.
No vendor advisory or patch details are supplied in the available references, which consist of a public GitHub disclosure, multiple Vuldb entries, and the vendor homepage. The EPSS score has remained flat at 0.0142 with no material rise since publication.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
