CVE-2025-6164
Published: 17 June 2025
Summary
CVE-2025-6164 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Totolink A3002R Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 19.4% 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 buffer overflow vulnerability tracked as CVE-2025-6164 affects the TOTOLINK A3002R router running firmware 4.0.0-B20230531.1404. The flaw resides in an unknown portion of the file /boafrm/formMultiAP within the HTTP POST Request Handler component, where improper handling of the submit-url argument can be manipulated to trigger the overflow. The issue is rated critical with a CVSS 4.0 score of 7.4 and is associated with CWE-119 and CWE-120.
An authenticated remote attacker can exploit the vulnerability by sending a specially crafted HTTP POST request to the affected endpoint. Successful exploitation may allow the attacker to execute arbitrary code or crash the device, with a public proof-of-concept already available.
The current EPSS score of 0.0136, with a peak of only 0.0137, indicates limited observed exploitation interest to date. No official vendor advisory or patch information is referenced in the available sources.

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.
