Adobe Acrobat Reader DC versions 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier are affected by a use-after-free vulnerability in the processing of the acroform event. This vulnerability allows arbitrary code execution in the context of the current user. Exploitation requires user interaction, as a victim must open a malicious file.
The CVSS score for this vulnerability is 7.8, categorizing it as high severity. Organizations should address this vulnerability in their priority patch cycle to mitigate potential risks. The exploitation of this issue poses a significant risk to users, particularly in environments where Adobe Acrobat Reader DC is widely used.
Given the nature of the vulnerability, attackers may leverage this weakness to execute arbitrary code, potentially leading to system compromise or data breaches. Thus, it is critical for organizations to remain vigilant and proactive in their security measures.
Organizations should prioritize patching immediately to eliminate this vulnerability and protect against potential exploitation.
Vulnerability Details
The vulnerability is classified under CWE-416, indicating a use-after-free issue. The CVSS base score is 7.8, indicating high severity, with a local attack vector and low attack complexity. No privileges are required for exploitation, but user interaction is necessary.
Affected products include Adobe Acrobat DC, Acrobat Reader DC, and their respective classic versions. This vulnerability was published on May 11, 2022, and has been modified since its initial disclosure.
Technical Analysis
The root cause of this vulnerability stems from improper handling of memory, specifically a use-after-free condition. This occurs when the memory is freed but still accessed, allowing attackers to manipulate the state of the application.
The attack vector is local, requiring the victim to open a malicious file. The attack complexity is low, with no special privileges required, but user interaction is essential. The impact on confidentiality, integrity, and availability is high, as successful exploitation could lead to arbitrary code execution.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant. Given that it requires user interaction, it may be exploited via social engineering tactics, such as phishing emails containing malicious attachments. Organizations that deploy Adobe Acrobat Reader DC widely are particularly vulnerable, as the blast radius could affect numerous systems if users are exploited.
With a CVSS score of 7.8 and an EPSS score indicating a 5% likelihood of exploitation, the urgency for remediation is high. Organizations should assess their environments for affected versions and prioritize updates.
