AlienVault OTX Vulnerabilities

AlienVault OTX Malware

An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.

CVE-2019-5094 is a high-severity vulnerability identified in the E2fsprogs utility suite, specifically affecting versions 1.43.3 through 1.45.3. E2fsprogs is a widely used set of tools for managing ext2/ext3/ext4 file systems on Linux and Unix-like operating systems. The vulnerability arises from an out-of-bounds write condition in the quota file functionality when processing specially crafted ext4 partitions. This flaw is classified under CWE-787, which refers to out-of-bounds writes that can corrupt memory beyond the intended buffer boundaries. Exploiting this vulnerability requires an attacker to create a malicious ext4 partition image that, when processed by vulnerable E2fsprogs utilities, triggers a heap-based buffer overflow. This overflow can lead to arbitrary code execution, allowing an attacker with sufficient privileges to execute malicious code in the context of the affected process. The CVSS v3.1 base score of 7.5 reflects the high impact on confidentiality, integrity, and availability, with the attack vector being local (AV:L), requiring high privileges (PR:H), no user interaction (UI:N), and scope change (S:C). The complexity is high (AC:H), indicating exploitation is non-trivial but feasible under certain conditions. While no known exploits have been reported in the wild, the potential for code execution makes this vulnerability critical to address in environments where E2fsprogs is used to manage ext4 partitions, especially in systems that handle untrusted disk images or partitions.
