CVE-2025-6130
Published: 16 June 2025
Summary
CVE-2025-6130 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 critical buffer overflow vulnerability has been identified in the TOTOLINK EX1200T wireless router running firmware version 4.1.2cu.5232_B20210713. The flaw resides in the HTTP POST Request Handler component, specifically within the unknown processing logic of the file /boafrm/formStats. It is tracked under CWE-119 and CWE-120 and carries a CVSS 4.0 score of 7.4.
An authenticated remote attacker can send a crafted HTTP POST request to the affected endpoint, triggering the overflow to achieve arbitrary code execution or a denial of service on the device. The attack requires no user interaction and can be launched over the network with low attack complexity.
Public proof-of-concept code has been disclosed via GitHub and the exploit is rated as available, yet the current EPSS remains low at 0.0136 with a peak of only 0.0137. No 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.
