CVE-2025-1897
Published: 04 March 2025
Summary
CVE-2025-1897 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Tx3 Firmware. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 22.8th percentile by exploit likelihood (below the median); 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-2 (Flaw Remediation).
Deeper analysis
CVE-2025-1897 is a critical buffer overflow vulnerability affecting Tenda TX3 firmware version 16.03.13.11_multi. The flaw occurs in the processing of the /goform/SetNetControlList file, where manipulation of the argument list triggers the overflow. It is associated with CWE-119 and CWE-120, and carries a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
The vulnerability enables remote exploitation by attackers possessing low privileges. Successful manipulation can lead to a denial of service due to the high availability impact, with low attack complexity and no requirement for user interaction.
Advisories are available via VulDB entries (ctiid.298415, id.298415, submit.506604) and a GitHub repository containing a PDF exploit for Tenda TX3 (https://github.com/2664521593/mycve/blob/main/Tenda/TX3/tenda_tx3_bof_3.pdf).
