CVE-2025-7417
Published: 10 July 2025
Summary
CVE-2025-7417 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda O3 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 stack-based buffer overflow vulnerability exists in Tenda O3V2 firmware version 1.0.0.12(3880). It resides in the fromNetToolGet function within the /goform/setPingInfo endpoint of the httpd component and is triggered by unsanitized input to the ip argument. The issue is tracked as CVE-2025-7417, carries a CVSS 4.0 score of 7.4, and is also associated with CWE-119 and CWE-121.
An authenticated attacker with network access can send a crafted HTTP request that overflows the stack buffer, leading to remote code execution or denial of service. The vulnerability can be triggered remotely without user interaction, and a working proof-of-concept has already been published.
Public references, including a detailed disclosure and exploit on GitHub together with corresponding Vuldb entries, confirm that the flaw has been made available to the public. No vendor advisory or patch information is referenced in the supplied sources.
The EPSS score remains flat at 0.0157 with no material increase since disclosure.
