https://notcve.org/view.php?id=CVE-2025-4876
19 May 2025 — ConnectWise-Password-Encryption-Utility.exe in ConnectWise Risk Assessment allows an attacker to extract a hardcoded AES decryption key via reverse engineering. This key is embedded in plaintext within the binary and used in cryptographic operations without dynamic key management. Once obtained the key can be used to decrypt CSV input files used for authenticated network scanning.

https://notcve.org/view.php?id=CVE-2025-3935
25 Apr 2025 — ScreenConnect versions 25.2.3 and earlier versions may be susceptible to a ViewState code injection attack. ASP.NET Web Forms use ViewState to preserve page and control state, with data encoded using Base64 protected by machine keys. It is important to note that to obtain these machine keys, privileged system level access must be obtained. If these machine keys are compromised, attackers could create and send a malicious ViewState to the website, potentially leading to remote code execution on the server.

13 Feb 2023 — In ConnectWise Control through 22.9.10032 (formerly known as ScreenConnect), after an executable file is signed, additional instructions can be added without invalidating the signature, such as instructions that result in offering the end user a (different) attacker-controlled executable file. It is plausible that the end user may allow the download and execution of this file to proceed. There are ConnectWise Control configuration options that add mitigations.

01 Feb 2023 — Connectwise Automate 2022.11 is vulnerable to Cleartext authentication. Authentication is being done via HTTP (cleartext) with SSL disabled. OTE: the vendor's position is that, by design, this is controlled by a configuration option in which a customer can choose to use HTTP (rather than HTTPS) during troubleshooting. • https://github.com/l00neyhacker/CVE-2023-23130 • CWE-319: Cleartext Transmission of Sensitive Information •

01 Feb 2023 — Connectwise Control 22.8.10013.8329 is vulnerable to Cross Origin Resource Sharing (CORS). The vendor's position is that two endpoints have Access-Control-Allow-Origin wildcarding to support product functionality, and that there is no risk from this behavior. The vulnerability report is thus not valid. • https://github.com/l00neyhacker/CVE-2023-23128 • CWE-942: Permissive Cross-domain Policy with Untrusted Domains •
