Apple Bonjour mDNSResponder.exe DLL Sideloading Vulnerability CVE-2022-23748
CVE-2022-23748 Published on November 17, 2022
mDNSResponder.exe is vulnerable to DLL Sideloading attack. Executable improperly specifies how to load the DLL, from which folder and under what conditions. In these scenarios, a malicious attacker could be using the valid and legitimate executable to load malicious files.
Known Exploited Vulnerability
This Dante Discovery Process Control Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Dante Discovery contains a process control vulnerability in mDNSResponder.exe that all allows for a DLL sideloading attack. A local attacker can leverage this vulnerability in the Dante Application Library to execute arbitrary code.
The following remediation steps are recommended / required by February 27, 2025: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Vulnerability Analysis
CVE-2022-23748 is exploitable with local system access, requires user interaction. This vulnerability is considered to have a low attack complexity. This vulnerability is known to be actively exploited by threat actors. The potential impact of an exploit of this vulnerability is considered to be very high.
Weakness Type
Process Control
Executing commands or loading libraries from an untrusted source or in an untrusted environment can cause an application to execute malicious commands (and payloads) on behalf of an attacker. Process control vulnerabilities take two forms: 1. An attacker can change the command that the program executes: the attacker explicitly controls what the command is. 2. An attacker can change the environment in which the command executes: the attacker implicitly controls what the command means. Process control vulnerabilities of the first type occur when either data enters the application from an untrusted source and the data is used as part of a string representing a command that is executed by the application. By executing the command, the application gives an attacker a privilege or capability that the attacker would not otherwise have.
