https://notcve.org/view.php?id=CVE-2023-25718
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. NOTE: this may overlap CVE-2023-25719. NOTE: the vendor's position is that this purported vulnerability represents a "fundamental lack of understanding of Authenticode code signing behavior." • https://cybir.com/2022/cve/connectwise-control-dns-spoofing-poc https://www.connectwise.com https://www.connectwise.com/blog/cybersecurity/the-importance-of-responsible-security-disclosures https://www.huntress.com/blog/clearing-the-air-overblown-claims-of-vulnerabilities-exploits-severity • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 1CVE-2023-25719
https://notcve.org/view.php?id=CVE-2023-25719
ConnectWise Control before 22.9.10032 (formerly known as ScreenConnect) fails to validate user-supplied parameters such as the Bin/ConnectWiseControl.Client.exe h parameter. This results in reflected data and injection of malicious code into a downloaded executable. The executable can be used to execute malicious queries or as a denial-of-service vector. NOTE: this CVE Record is only about the parameters, such as the h parameter (this CVE Record is not about the separate issue of signed executable files that are supposed to have unique configurations across customers' installations). • https://cybir.com/2022/cve/hijacking-connectwise-control-and-ddos https://www.connectwise.com https://www.connectwise.com/blog/cybersecurity/the-importance-of-responsible-security-disclosures https://www.huntress.com/blog/clearing-the-air-overblown-claims-of-vulnerabilities-exploits-severity • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
