Adobe Acrobat Reader versions 22.001.20169 (and earlier), 20.005.30362 (and earlier), and 17.012.30249 (and earlier) are affected by a Use After Free vulnerability. This vulnerability allows arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction, as the victim must open a malicious file. Given the potential impacts, organizations must take immediate action.
The vulnerability has a CVSS score of 7.8, indicating a high severity level. This score highlights the significant risk to organizations, as it allows attackers to execute arbitrary code with the same privileges as the user. The urgency to address this vulnerability is underscored by its potential for widespread exploitation.
Organizations should prioritize patching immediately. The risk landscape associated with this vulnerability necessitates proactive measures to protect sensitive data and maintain operational integrity.
As of now, there are no known exploits or public proofs of concept available for this vulnerability. However, the nature of the issue suggests that it could be targeted by threat actors, especially given the requirement for user interaction to initiate the attack.
In light of the potential risks and the current exploitation status, organizations are advised to address this vulnerability in their priority patch cycle.
Vulnerability Details
The vulnerability is classified as a Use After Free issue, as described in the official CVE documentation. The affected products include Adobe Acrobat and Adobe Acrobat Reader across various versions, as detailed in the CVSS vector string: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. This indicates that the attack vector is local, and the complexity is low, requiring no privileges but necessitating user interaction.
Technical Analysis
The root cause of this vulnerability lies in improper handling of memory, leading to the potential for arbitrary code execution. The attack vector is local, meaning an attacker must have access to the victim's system, either physically or via a local network. The attack complexity is classified as low, as it does not require advanced skills. No privileges are required to exploit this vulnerability, and user interaction is necessary, as the victim must open the malicious file.
The impacts of this vulnerability are significant, affecting confidentiality, integrity, and availability, all rated as high. An attacker successfully exploiting this vulnerability can gain complete control over the affected system, leading to severe consequences for the organization.
Risk & Impact Analysis
The real-world risk associated with this vulnerability includes potential unauthorized system access and arbitrary code execution, which could lead to data breaches, loss of sensitive information, or system compromise. The blast radius is extensive, as many organizations utilize Adobe Acrobat and Reader in their workflows.
Given the high CVSS score and the absence of known public exploits, it is critical for organizations to assess their exposure and take immediate steps to mitigate the risks associated with this vulnerability.
