Vulnerability due to incorrect permissions in TSplus Remote Access shared login scripts. The autostart1.tscr files, located in the shared themes directory, allow users without sufficient privileges to write to them. A local attacker with a valid session on the terminal or remote desktop server could modify these files to execute arbitrary commands within another user’s security context when that user logs in using the same theme or operating mode. Depending on the affected user’s privileges, exploitation could allow lateral movement between users or privilege escalation.

Incorrect authentication vulnerability in the TSplus Remote Access multi-factor authentication (MFA) mechanism. A remote attacker authenticated with valid first-factor credentials could bypass the second-factor verification because the authentication flow does not correctly apply the MFA validation result, allowing the attacker to complete the login without a valid second-factor token and gain access to protected applications and resources.

A vulnerability involving improper access control in the TSplus Remote Access web server that allows an unauthenticated remote attacker to access internal resources protected by manipulated paths through the /socket.io/JWN/ endpoint, bypassing the access restrictions intended for certain internal resources.

Access to TSplus Remote Access Admin Tool is restricted to administrators (unless "Disable UAC" option is enabled) and requires a PIN code. In versions below v18.40.6.17 the PIN's hash is stored in a system registry accessible to regular users, making it possible to perform a brute-force attack using rainbow tables, since the hash is not salted. LTS (Long-Term Support) versions also received patches in v17.2025.6.27 and v16.2025.6.27 releases.

hb.exe in TSplus Remote Access before 17.30 2024-10-30 allows remote attackers to retrieve a list of all domain accounts currently connected to the application.

TSplus Remote Work 16.0.0.0 has weak permissions for .exe, .js, and .html files under the %PROGRAMFILES(X86)%\TSplus-RemoteWork\Clients\www folder. This may enable privilege escalation if a different local user modifies a file. NOTE: CVE-2023-31067 and CVE-2023-31068 are only about the TSplus Remote Access product, not the TSplus Remote Work product.
