CVE-2025-7598
Published: 14 July 2025
Summary
CVE-2025-7598 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ax1803 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 critical stack-based buffer overflow vulnerability exists in Tenda AX1803 firmware version 1.0.0.1. It resides in the formSetWifiMacFilterCfg function of the /goform/setWifiFilterCfg endpoint and is triggered by unsanitized input to the deviceList argument, corresponding to CWE-119 and CWE-121.
An authenticated attacker with network access can send a crafted HTTP request to the affected endpoint and achieve remote code execution or a full device compromise. The CVSS 4.0 vector reflects network attack reach, low complexity, and high impact on confidentiality, integrity, and availability, with a publicly disclosed proof-of-concept available.
Public references consist of exploit details and PoC code hosted on GitHub along with VulDB entries; no vendor advisory or patch information is provided in the references. The EPSS score remains flat at 0.0157 with no observed rise after disclosure.
