AlienVault OTX Vulnerabilities

AlienVault OTX Malware

CVE-2025-47205 is a medium-severity NULL pointer dereference vulnerability affecting QNAP QTS operating system versions 5.2.x. An attacker with administrator privileges can exploit this flaw to cause a denial-of-service (DoS) condition, disrupting system availability. The vulnerability does not require user interaction and has a CVSS 4.0 base score of 5.1, indicating moderate risk. It has been fixed in QTS 5.2.8.

CVE-2025-47205 is a NULL pointer dereference vulnerability classified under CWE-476, affecting QNAP Systems Inc.'s QTS operating system, specifically versions in the 5.2.x series. This vulnerability arises when the system dereferences a NULL pointer, leading to a crash or denial-of-service condition. Exploitation requires the attacker to have already obtained administrator-level access to the QTS system, which means the vulnerability itself is not remotely exploitable without prior privilege escalation or credential compromise. Once exploited, the attacker can trigger a DoS by causing the system to crash or become unresponsive, impacting availability of the NAS device and any services relying on it. The vulnerability does not affect confidentiality or integrity directly but can disrupt business operations due to service outages. The vendor has addressed the issue in QTS 5.2.8.3332 build 20251128 and QuTS hero h5.2.8.3321 build 20251117 and later versions. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required for the attack itself (AT:N), but privileges are required (PR:H) to exploit, no user interaction (UI:N), and low impact on availability (VA:L). No known exploits have been reported in the wild, suggesting limited active exploitation currently. However, the presence of administrative access as a prerequisite means that organizations with weak credential management or exposed management interfaces are at risk. The vulnerability highlights the importance of patch management and securing administrative accounts on QNAP NAS devices.
