Summary

CVE-2025-7116 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Utt 750W Firmware. Its CVSS base score is 7.4 (High).

Operationally, ranked in the top 15.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

CVE-2025-7116 is a critical buffer overflow vulnerability affecting the UTT 进取 750W wireless router up to version 3.2.2-191225. It resides in an unknown portion of the /goform/Fast_wireless_conf endpoint, where improper handling of the ssid argument triggers the flaw, classified under CWE-119 and CWE-120. The issue can be triggered remotely and carries a CVSS 4.0 score of 7.4.

An authenticated remote attacker with low privileges can supply a malicious ssid value to the endpoint, leading to memory corruption that may enable arbitrary code execution or a crash of the affected device. Public proof-of-concept code demonstrating the attack has already been released.

The vendor was notified prior to disclosure but provided no response, and the listed references contain no information on patches, workarounds, or official mitigation guidance. The associated EPSS score has remained flat at 0.0222 with no observed increase.

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.
