Summary

CVE-2025-6150 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Totolink X15 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 affects the TOTOLINK X15 router running firmware version 1.0.0-B20230714.1105. The flaw resides in an unknown function within the file /boafrm/formMultiAP of the HTTP POST Request Handler component, where improper handling of the submit-url argument allows an attacker to trigger memory corruption via CWE-119 and CWE-120.

The vulnerability can be exploited remotely by an authenticated attacker who sends a crafted HTTP POST request to the affected endpoint. Successful exploitation grants the attacker the ability to execute arbitrary code or crash the device, with the public proof-of-concept demonstrating remote code execution potential under the CVSS 7.4 rating.

Public references consist of a disclosed proof-of-concept on GitHub and corresponding Vuldb entries, but no vendor advisory or patch information is provided in the available sources. The EPSS score remains low and essentially flat at approximately 0.0136–0.0137, indicating limited observed exploitation interest following disclosure.

Mitigating Controls

Likely Mitigating Controls AI

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.

addresses: CWE-119 CWE-120

Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.

addresses: CWE-119

Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.

addresses: CWE-119

Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.

addresses: CWE-119

Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
