CVE-2025-7596
Published: 14 July 2025
Summary
CVE-2025-7596 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Fh1205 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 18.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
A vulnerability rated critical exists in Tenda FH1205 version 2.0.0.7(775). It resides in the formWifiExtraSet function of the /goform/WifiExtraSet endpoint, where improper handling of the wpapsk_crypto argument produces a stack-based buffer overflow. The flaw is tracked under CWE-119, CWE-121, and CWE-787 and carries a CVSS 4.0 score of 7.4 reflecting network attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
An authenticated remote attacker can supply a crafted wpapsk_crypto value to trigger the overflow, leading to arbitrary code execution or denial of service on the affected device. Public proof-of-concept code demonstrating the issue has already been released.
The EPSS score remains flat at 0.0157 with no material increase after disclosure, indicating limited observed exploitation interest to date.
