CVE-2022-28268 is a low-severity vulnerability affecting multiple versions of Adobe Acrobat Reader DC, including versions 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier. This vulnerability allows for an out-of-bounds read that could potentially lead to the disclosure of sensitive memory. An attacker may exploit this vulnerability to bypass mitigations such as ASLR (Address Space Layout Randomization). It is important to note that exploitation requires user interaction, specifically that the victim must open a malicious file.
The vulnerability has been assigned a CVSS score of 3.3, indicating a low severity. Despite its low score, the potential for sensitive information disclosure remains a concern for users and organizations. Given that exploitation depends on user action, it emphasizes the need for security awareness and training regarding the dangers of opening unknown or untrusted files.
Organizations should prioritize patching this vulnerability as part of their risk management strategy. Although it may not pose an immediate threat, the implications of unauthorized access to sensitive data warrant timely remediation efforts.
As of now, there are no known exploits in the wild, and Adobe has released updates to address this issue. Users are encouraged to update their software to the latest version to mitigate the risk associated with this vulnerability.
Vulnerability Details
The vulnerability description states that Acrobat Reader DC versions 22.001.20085 (and earlier), 20.005.3031x (and earlier), and 17.012.30205 (and earlier) are affected. The root cause is categorized under CWE-125, which relates to out-of-bounds read vulnerabilities. The official Adobe advisory provides more context on the affected versions and the nature of the vulnerability.
Technical Analysis
The root cause of CVE-2022-28268 is an out-of-bounds read vulnerability within Adobe Acrobat Reader DC. The attack vector is local, meaning that an attacker must have physical or remote access to the target system to exploit this vulnerability. The attack complexity is low, and the privileges required for exploitation are nonexistent, as no prior authentication is required. However, user interaction is mandatory, as the victim must open a specially crafted malicious file to trigger the vulnerability.
The impact of this vulnerability is classified as low in terms of confidentiality, integrity, and availability, with confidentiality potentially being affected due to the exposure of sensitive memory contents. Given the low severity, the effects may not be immediately catastrophic, but they can still lead to significant security breaches if exploited.
Risk & Impact Analysis
Risk to organizations includes the potential for sensitive data exposure, which could be leveraged for further attacks or data breaches. The blast radius is relatively contained due to the necessity of user interaction, but organizations should not underestimate the implications of unauthorized access to sensitive information. Given the CVSS score of 3.3 and the EPSS score of approximately 0.03, the urgency for remediation is low, but it should still be addressed to maintain a robust security posture.
