CVE-2026-67248: CWE-121 Stack-based buffer overflow in ASUSTOR Inc. ADM
A stack-based buffer overflow vulnerability was found in the File Explorer on the ADM. The vulnerability occurs because user-controlled input is not properly validated before being decoded and copied into a fixed-size stack buffer. An authenticated attacker can exploit this issue to cause denial of service of the affected CGI process. Further impact may be possible depending on exploitability and runtime protections. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.
AI Analysis
Technical Summary
CVE-2026-67248 is a stack-based buffer overflow vulnerability in the File Explorer of ASUSTOR Inc.'s ADM software. The vulnerability is due to insufficient validation of user input before it is decoded and copied into a fixed-size stack buffer, leading to potential memory corruption. Exploitation requires authentication and can cause denial of service of the CGI process handling the input. The vulnerability affects ADM versions 4.1.0 through 4.3.3.RUN1 and 5.0.0 through 5.1.3.RI81. There is no vendor advisory indicating an available patch or fix at this time.
Potential Impact
An authenticated attacker can exploit this vulnerability to cause a denial of service condition in the affected CGI process of ADM. Further impact is possible depending on exploitability and runtime protections, but no confirmed exploits in the wild are reported. The CVSS 4.0 base score is 8.7 (high severity), reflecting network attack vector, low attack complexity, no user interaction, and high impacts on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the ADM File Explorer to trusted users only and monitor for unusual activity. No official remediation or temporary fix has been published by ASUSTOR Inc. at this time.
