CVE-2025-4299
Published: 06 May 2025
Summary
CVE-2025-4299 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ac1206 Firmware. Its CVSS base score is 8.7 (High).
Operationally, ranked in the top 19.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A vulnerability rated critical has been identified in Tenda AC1206 wireless routers running firmware up to version 15.03.06.23. The flaw exists in the setSchedWifi function of the /goform/openSchedWifi endpoint and stems from improper bounds checking that permits a buffer overflow, tracked under CWE-119 and CWE-120.
An authenticated attacker with network access can exploit the issue remotely by supplying crafted input to the affected endpoint. Successful exploitation can result in arbitrary code execution or full device compromise, consistent with the CVSS 8.7 vector that emphasizes high impact on confidentiality, integrity, and availability.
Public proof-of-concept code has been published, confirming the vulnerability is known and usable, yet the EPSS score has remained flat at 0.0133 with no material rise since disclosure. Available references point to a GitHub repository containing exploit details and the vendor site but contain no information on patches or specific mitigation steps.

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.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
