BeyondTrust Privileged Remote Access (PRA) versions prior to 25.1 are vulnerable to a local authentication bypass. A local authenticated attacker can view the connection details of a ShellJump session that was initiated with external tools, allowing unauthorized access to connected sessions.

The Challenge Response feature of BeyondTrust Privilege Management for Windows (PMfW) before 2023-07-14 allows local administrators to bypass this feature by decrypting the shared key, or by locating the decrypted shared key in process memory. The threat is mitigated by the Agent Protection feature.

An issue was discovered in BeyondTrust Privilege Management for Windows through 5.6. If the publisher criteria is selected, it defines the name of a publisher that must be present in the certificate (and also requires that the certificate is valid). If an Add Admin token is protected by this criteria, it can be leveraged by a malicious actor to achieve Elevation of Privileges from standard user to administrator.

An issue was discovered in BeyondTrust Privilege Management for Windows through 5.6. When specifying a program to elevate, it can typically be found within the Program Files (x86) folder and therefore uses the %ProgramFiles(x86)% environment variable. However, when this same policy gets pushed to a 32bit machine, this environment variable does not exist. Therefore, since the standard user can create a user level environment variable, they can repoint this variable to any folder the user has full control of. Then, the folder structure can be created in such a way that a rule matches and arbitrary code runs elevated.

An issue was discovered in BeyondTrust Privilege Management for Windows through 5.6. When adding the Add Admin token to a process, and specifying that it runs at medium integrity with the user owning the process, this security token can be stolen and applied to arbitrary processes.

An issue was discovered in BeyondTrust Privilege Management for Mac before 5.7. An authenticated, unprivileged user can elevate privileges by running a malicious script (that executes as root from a temporary directory) during install time. (This applies to macOS before 10.15.5, or Security Update 2020-003 on Mojave and High Sierra, Later versions of macOS are not vulnerable.)

An issue was discovered in BeyondTrust Privilege Management for Windows through 5.6. An attacker can spawn a process with multiple users as part of the security token (prior to Avecto elevation). When Avecto elevates the process, it removes the user who is launching the process, but not the second user. Therefore this second user still retains access and can give permission to the process back to the first user.

BeyondTrust Privileged Remote Access (PRA) versions 22.2.x to 22.4.x are vulnerable to a local authentication bypass. Attackers can exploit a flawed secret verification process in the BYOT shell jump sessions, allowing unauthorized access to jump items by guessing only the first character of the secret.

BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) versions 23.2.1 and 23.2.2 contain a command injection vulnerability which can be exploited through a malicious HTTP request. Successful exploitation of this vulnerability can allow an unauthenticated remote attacker to execute underlying operating system commands within the context of the site user. This issue is fixed in version 23.2.3.
