CVE-2025-6098
Published: 16 June 2025
Summary
CVE-2025-6098 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 8.9 (High).
Operationally, ranked in the top 21.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A buffer overflow vulnerability exists in the UTT 进取 750W router up to version 5.0, specifically in the strcpy function within the /goform/setSysAdm API endpoint. The flaw is triggered by unsanitized input to the passwd1 argument and is tracked under CWE-119 and CWE-120. It carries a CVSS 4.0 score of 8.9 and permits unauthenticated remote exploitation.
An attacker can send a crafted HTTP request to the affected endpoint over the network to overflow the buffer, potentially achieving arbitrary code execution or full device compromise. The attack requires no user interaction or credentials, and a working proof-of-concept has already been published.
Public references include a detailed disclosure and exploit on GitHub together with Vuldb entries that note the vendor was contacted prior to publication but provided no response or patch. The associated EPSS score has remained flat at 0.0112 with no observed increase since disclosure.

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.
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.
