CVE-2025-6144
Published: 16 June 2025
Summary
CVE-2025-6144 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 wireless range extender running firmware version 4.1.2cu.5232_B20210713. The issue resides in an unknown function within the file /boafrm/formSysCmd of the HTTP POST Request Handler component. Improper handling of the submit-url argument triggers a buffer overflow, tracked under CWE-119 and CWE-120, with a CVSS 4.0 score of 7.4 reflecting network-accessible impact on confidentiality, integrity, and availability.
An authenticated remote attacker can send a crafted HTTP POST request to the affected endpoint, causing memory corruption that may lead to arbitrary code execution or denial of service. Public proof-of-concept code has been released, confirming the flaw is exploitable over the network without user interaction beyond valid credentials.
The associated EPSS score remains low at approximately 0.0136 with negligible movement from its recorded peak, indicating limited observed exploitation interest to date. Available references consist of technical descriptions and exploit artifacts hosted on public repositories, with no vendor advisory or patch information provided in the current disclosures.

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.
