AlienVault OTX Malware

asyncssh

An issue in AsyncSSH before 2.14.1 allows attackers to control the remote end of an SSH client session via packet injection/removal and shell emulation, aka a "Rogue Session Attack."

CVE-2023-46446 is a security vulnerability identified in AsyncSSH, an open-source Python library used to implement SSH clients and servers. The vulnerability affects versions before 2.14.1 and allows attackers to perform a Rogue Session Attack by injecting or removing packets within an SSH client session and leveraging shell emulation techniques. This manipulation can enable an attacker to take control of the remote end of an SSH client session, effectively hijacking the session or altering its behavior without the user's knowledge. The attack exploits weaknesses in how AsyncSSH processes and validates SSH packets, allowing unauthorized control over the session's data stream. This can lead to unauthorized command execution, data interception, or session disruption. No CVSS score has been assigned yet, and there are no known exploits actively used in the wild. However, the vulnerability's nature suggests a critical impact on confidentiality and integrity of SSH communications. The flaw is particularly concerning because SSH is widely used for secure remote administration and data transfer, making any compromise potentially severe. The vulnerability requires network-level access to the SSH session but does not require prior authentication to the target system, increasing its risk profile. The fix involves updating AsyncSSH to version 2.14.1 or later, where the packet handling and session management have been corrected to prevent such manipulation.
