CVE-2024-48293 is a vulnerability identified in QuickHeal Antivirus Pro version 24.1.0.182 and earlier, caused by incorrect access control mechanisms (CWE-276). The flaw allows authenticated users with low-level privileges to modify antivirus settings arbitrarily. This means that an attacker who has gained limited access to a system can escalate their influence by changing security configurations, potentially disabling or weakening antivirus protections. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The CVSS v3.1 base score is 6.5, reflecting a medium severity primarily due to the high impact on integrity (I:H) but no impact on confidentiality (C:N) or availability (A:N). The vulnerability is significant because antivirus settings control critical defense mechanisms; unauthorized changes can lead to further compromise or persistence of malware. No patches or known exploits are currently available, but the risk remains until a fix is released. The vulnerability was reserved in early October 2024 and published in mid-November 2024, indicating recent discovery and disclosure.

The primary impact of CVE-2024-48293 is on the integrity of antivirus configurations. Attackers with low privileges can weaken or disable antivirus protections, increasing the risk of malware infections, data manipulation, or persistence of malicious code. While confidentiality and availability are not directly affected, the indirect consequences can be severe, as compromised antivirus settings can facilitate broader attacks. Organizations relying on QuickHeal Antivirus Pro are at risk of internal threat actors or attackers who have gained limited access escalating their control. This vulnerability could be exploited in enterprise environments, especially where endpoint security is critical. The lack of required user interaction and low complexity of exploitation increase the likelihood of successful attacks once an attacker has authenticated access. The absence of known exploits in the wild currently limits immediate risk but does not eliminate future exploitation potential.

Until an official patch is released, organizations should implement strict access controls to limit low-privilege user capabilities on systems running QuickHeal Antivirus Pro. This includes enforcing the principle of least privilege, ensuring users do not have unnecessary rights to modify security settings. Monitoring and alerting on changes to antivirus configurations can help detect exploitation attempts early. Network segmentation and strong authentication mechanisms can reduce the risk of unauthorized access. Additionally, organizations should maintain up-to-date backups and have incident response plans ready in case of compromise. Once a patch becomes available, prompt deployment is critical. Vendors and users should also verify the integrity of antivirus software installations and consider temporary compensating controls such as application whitelisting or enhanced endpoint detection and response (EDR) solutions to mitigate risks.
