CVE-2025-7117
Published: 07 July 2025
Summary
CVE-2025-7117 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Utt 840G Firmware. Its CVSS base score is 7.4 (High).
Operationally, ranked in the top 18.0% 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 exists in UTT HiPER 840G up to version 3.1.1-190328, specifically in the unknown code of the file /goform/websWhiteList. Manipulation of the addHostFilter argument triggers the flaw, which is tracked under CWE-119 and CWE-120 and carries a CVSS 4.0 score of 7.4 reflecting network attack vector, low complexity, and low privileges required.
The issue can be exploited remotely by an authenticated attacker to corrupt memory and potentially execute arbitrary code or cause denial of service. Public proof-of-concept code has been released, confirming the attack path and indicating that exploitation is feasible without user interaction.
Available references consist of GitHub disclosure entries containing the proof-of-concept and Vuldb records; the vendor was notified prior to publication but provided no response, and no official patches or mitigation guidance appear in the referenced sources.
The EPSS score sits at 0.0159 with an identical peak value, showing no material rise after disclosure.

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.
