Adobe Acrobat Reader DC versions 22.001.20085 and earlier, along with versions 20.005.3031x and 17.012.30205 and earlier, are affected by a high-severity use-after-free vulnerability. This vulnerability allows arbitrary code execution in the context of the current user, posing significant risks to organizations. The exploitation of this vulnerability requires user interaction, as a victim must open a malicious file to trigger the issue.
With a CVSS score of 7.8, this vulnerability falls under the high severity category. Organizations should prioritize patching immediately to mitigate potential exploitation. The risk to organizations includes unauthorized access and potential data compromise, thus highlighting the importance of swift remediation.
Currently, there is no public exploit available for this vulnerability, but the potential for exploitation remains high due to its nature. Organizations are urged to address this vulnerability in their patch management processes to prevent possible attacks.
In light of the above, it is essential for organizations to schedule remediation efforts as part of their regular security protocols, ensuring that all affected systems are updated to the latest secure versions.
Vulnerability Details
The vulnerability identified as CVE-2022-28230 is classified as a use-after-free vulnerability, which can allow attackers to execute arbitrary code. The vulnerability affects Adobe Acrobat Reader DC and related products, as detailed in the official description provided by Adobe.
The CVSS score assigned to this vulnerability is 7.8, indicating a high level of severity. The primary impact includes high confidentiality, integrity, and availability concerns, making this a critical issue for users of the affected software.
The affected products include Adobe Acrobat and Adobe Acrobat Reader versions as mentioned earlier, with publication of this vulnerability on May 11, 2022.
Technical Analysis
The root cause of this vulnerability lies in improper memory management during the processing of the acroform event in Adobe Acrobat products. This can lead to a use-after-free condition, allowing attackers to execute arbitrary code when the vulnerable software is manipulated.
The attack vector is categorized as local, meaning an attacker must have access to the user's environment. The attack complexity is low, indicating that basic user interaction is sufficient to trigger the vulnerability. No privileges are required to exploit this vulnerability, but user interaction is necessary to open a malicious file.
In terms of impact, the vulnerability can compromise confidentiality, integrity, and availability, making it a significant risk for organizations using Adobe Acrobat products.
Risk & Impact Analysis
The potential risks stemming from CVE-2022-28230 include the possibility of unauthorized code execution, which could lead to a variety of malicious activities, such as data theft, system compromise, or further propagation of malware. Given the high CVSS score and the exploitation requirements, organizations should treat this issue with urgency.
The blast radius for this vulnerability is substantial, as it affects multiple versions of Adobe Acrobat and Reader, widely used in corporate environments. Organizations should assess their deployment of the affected products and prioritize updates as part of a comprehensive security strategy.
Considering the current landscape of software vulnerabilities and the increasing sophistication of attacks, the urgency for remediation based on the CVSS score and the potential impact on organizational operations is high.
