CVE-2025-52907
Published: 24 September 2025
Summary
CVE-2025-52907 is a high-severity Improper Input Validation (CWE-20) vulnerability in Totolink X6000R Firmware. Its CVSS base score is 7.3 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 46.1% 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-2 (Flaw Remediation).
Deeper analysis
CVE-2025-52907 is an improper input validation flaw, tracked under CWE-20, that affects the TOTOLINK X6000R router in all versions through V9.4.0cu.1360_B20241207. The vulnerability permits command injection and file manipulation on the device.
An unauthenticated remote attacker can trigger the flaw over the network, though the CVSS vector indicates user interaction is required and attack complexity is high. Successful exploitation grants the ability to inject commands and manipulate files, resulting in high integrity impact on the device along with secondary impacts to confidentiality and availability in the surrounding environment.
The referenced Palo Alto Networks disclosure and TOTOLINK firmware page provide the primary sources for mitigation details and updated firmware. EPSS for the CVE rose from a low baseline to a peak of 0.0106, indicating emerging exploitation interest after public disclosure.
