CVE-2025-7118
Published: 07 July 2025
Summary
CVE-2025-7118 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 18.5% 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 firmware up to version 3.1.1-190328. The flaw resides in the handling of the importpictureurl argument to the /goform/formPictureUrl endpoint and is tracked under CWE-119 and CWE-120. Remote attackers can trigger the condition without user interaction.
An authenticated attacker with network access can supply a crafted value to overflow the buffer, resulting in high impact to confidentiality, integrity, and availability on the device. Public proof-of-concept code has been released, and the vendor did not respond to early disclosure notification.
The EPSS score remains flat at 0.0149 with no material increase after publication, indicating limited observed exploitation interest to date.

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.
