CVE-2022-2313 is a high-severity DLL hijacking vulnerability affecting McAfee Agent versions prior to 5.7.7. This vulnerability allows local users to execute arbitrary code and obtain higher privileges by carefully placing a malicious DLL in the folder from which the Smart Installer is executed. With a CVSS score of 8.2, this vulnerability poses significant risks to organizations, especially given the local attack vector and low complexity required for exploitation.
The urgency for defenders is critical. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. As local users can exploit this, the potential impact on confidentiality, integrity, and availability can be severe, making swift remediation essential.
Currently, there are no known public exploits for CVE-2022-2313, but its high exploitability score and the nature of the vulnerability indicate that it could be targeted by attackers. Organizations must remain vigilant and ensure their systems are updated to the latest versions to avoid falling victim to this threat.
In summary, CVE-2022-2313 represents a significant risk due to its potential for privilege escalation via local exploitation. Organizations operating versions of McAfee Agent prior to 5.7.7 must take immediate action to safeguard their systems.
Vulnerability Details
This vulnerability allows local users to execute arbitrary code and obtain higher privileges via careful placement of a malicious DLL into the folder from where the Smart Installer is being executed. The official CVE description indicates that it is a DLL hijacking vulnerability affecting McAfee Agent versions prior to 5.7.7.
The vulnerability has a CVSS score of 8.2, classified as high severity. The attack vector is local, and it has low attack complexity with low privileges required. User interaction is required for exploitation, and it has a changed scope with a high impact on confidentiality, integrity, and availability.
The vulnerability has been assigned CWE-427, indicating a DLL hijacking issue. The affected product is the McAfee Agent.
Technical Analysis
The root cause of CVE-2022-2313 stems from the way the MA Smart Installer for Windows handles DLL files. Attackers can exploit this flaw by placing a malicious DLL alongside the legitimate installer. When the installer is executed, it inadvertently loads the malicious DLL, allowing the attacker to execute arbitrary code.
The attack vector is local, meaning that the attacker must have local access to the machine where the installer is executed. The attack complexity is low, as it does not require advanced techniques to exploit. Low privileges are necessary, and user interaction is required to start the installer.
The impacts are significant, with confidentiality, integrity, and availability all at risk. Successful exploitation can lead to unauthorized access and control over the affected system.
Risk & Impact Analysis
Organizations utilizing McAfee Agent versions prior to 5.7.7 face substantial risks due to CVE-2022-2313. The potential for local users to execute arbitrary code can lead to significant disruptions and unauthorized access to sensitive information. The blast radius of this vulnerability is considerable, as it can affect any system running the vulnerable version of the software.
Given the high CVSS score, organizations should assess their urgency to remediate this vulnerability as high. Immediate action is recommended to patch systems and mitigate risks. The potential for exploitation in environments where the software is widely deployed increases the urgency for organizations to address this issue.
In conclusion, the risks associated with CVE-2022-2313 necessitate prompt and effective remediation strategies to protect organizational assets from potential exploitation.

Affected Versions
The affected versions are all versions of McAfee Agent prior to 5.7.7. Organizations should review their systems and ensure they are upgraded to this version or later to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
To remediate CVE-2022-2313, organizations should patch their systems by upgrading to McAfee Agent version 5.7.7 or later. If a patch is not immediately available, organizations should implement workarounds such as restricting access to the installer directory and monitoring for unusual DLLs being placed in these locations.
Configuration hardening should be considered to limit the execution of unauthorized applications. Organizations may also implement network controls to restrict local access to systems running vulnerable versions of the McAfee Agent.
Continuous security testing practices should be adopted to identify and address similar vulnerabilities in the future. Organizations can validate remediation effectiveness through continuous security testing that exercises the patched code path.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized DLL placements and execution. Behavioral anomalies such as unexpected application behavior or unauthorized access attempts should be investigated. Network signatures can also be employed to detect local exploitation attempts of the Smart Installer.
AppSecure Threat Intelligence Insight
