Published: 14 July 2025
Summary
CVE-2025-7597 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, tracked as CVE-2025-7597, affects the Tenda AX1803 router at firmware version 1.0.0.1. The flaw exists in the formSetMacFilterCfg function of the /goform/setMacFilterCfg endpoint, where unsanitized input to the deviceList argument can corrupt the stack.
An authenticated remote attacker can trigger the overflow by submitting a crafted HTTP request to the management interface, leading to arbitrary code execution or a device crash. The vulnerability is rated 7.4 under CVSS 4.0 and is accompanied by a publicly disclosed proof-of-concept.
No vendor advisories or official patches are referenced in the available sources. The EPSS score has remained flat at 0.0157 with no material rise after disclosure.
