Published: 26 July 2025
Summary
CVE-2025-8180 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ch22 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 18.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
A critical buffer overflow vulnerability exists in Tenda CH22 version 1.0.0.1 within the formdeleteUserName function of the /goform/deleteUserName endpoint. The issue stems from improper handling of the old_account argument, classified under CWE-119 and CWE-120, and carries a CVSS 4.0 score of 7.4 reflecting network-accessible attack vectors with high impact on confidentiality, integrity, and availability.
An authenticated remote attacker can supply a crafted old_account value to trigger the overflow. Successful exploitation may allow arbitrary code execution or system compromise, and a public exploit for this flaw has already been disclosed.
The associated EPSS score remains flat at 0.0155 with no material increase since disclosure. Reference materials point to a GitHub proof-of-concept and VulDB entries but contain no vendor-supplied patch or mitigation guidance at this time.
