AlienVault OTX Vulnerabilities

AlienVault OTX Malware

Tenda CP3 Pro Firmware V22.5.4.93 contains a hardcoded root password hash in the /etc/passwd file and /etc/passwd-. An attacker with access to the firmware image can extract and attempt to crack the root password hash, potentially obtaining administrative access

CVE-2025-52363 is a vulnerability identified in the firmware of the Tenda CP3 Pro router, specifically version V22.5.4.93. The issue arises from the presence of a hardcoded root password hash embedded within the /etc/passwd and /etc/passwd- files of the firmware image. This means that anyone with access to the firmware image can extract this password hash and attempt to crack it offline. If successful, the attacker gains root-level administrative access to the device. Root access on a router allows full control over the device, including the ability to modify configurations, intercept or redirect network traffic, install persistent malware, or use the device as a foothold for further attacks within the network. The vulnerability does not require the attacker to have prior access to the device itself; possession of the firmware image alone is sufficient to start an attack. Although no known exploits are currently reported in the wild, the presence of a hardcoded root password hash is a critical security flaw that significantly lowers the barrier for attackers to compromise affected devices once the password hash is cracked. The lack of a CVSS score indicates that this vulnerability has not yet been formally scored, but the technical details suggest a high-risk issue due to the potential for full device compromise and network infiltration.
