BeyondTrust Remote Support (RS) and certain older versions of Privileged Remote Access (PRA) contain a critical pre-authentication remote code execution vulnerability. By sending specially crafted requests, an unauthenticated remote attacker may be able to execute operating system commands in the context of the site user.

A critical vulnerability has been discovered in Privileged Remote Access (PRA) and Remote Support (RS) products which can allow an unauthenticated attacker to inject commands that are run as a site user.

BeyondTrust Remote Support contains an authentication bypass by spoofing vulnerability that could allow a remote attacker to perform file operations on the appliance.

A heap-based buffer overflow was found in the way sudo parses command line arguments.

As per the researcher this vulnerability:

- is exploitable by any local user (normal users and system users, sudoers and non-sudoers), without authentication (i.e., the attacker does not need to know the user's password);

- was introduced in July 2011 (commit 8255ed69), and affects all legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, in their default configuration.

This could lead to privilege escalation.

A vulnerability has been discovered in Privileged Remote Access (PRA) and Remote Support (RS) which can allow an attacker with existing administrative privileges to inject commands and run as a site user.
