CVE-2025-6162
Published: 17 June 2025
Summary
CVE-2025-6162 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Totolink Ex1200T 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 vulnerability classified as critical has been identified in the TOTOLINK EX1200T firmware version 4.1.2cu.5232_B20210713. It resides in an unknown function within the /boafrm/formMultiAP file of the HTTP POST Request Handler component. The issue stems from improper handling of the submit-url argument, resulting in a buffer overflow condition tracked under CWE-119 and CWE-120.
The flaw can be exploited remotely by an authenticated attacker who sends a crafted HTTP POST request. Successful exploitation grants the ability to execute arbitrary code or crash the affected device, with the public proof-of-concept confirming remote code execution potential under the CVSS 7.4 rating.
Public references consist of a disclosed exploit on GitHub along with VulDB entries that document the issue but provide no vendor patch or mitigation guidance. The associated EPSS score remains low at approximately 0.0136 with negligible change from its recorded peak.

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.
