Source: CVE
Vendor/Project: Adobe
Product: InCopy

Description

Adobe InCopy version 17.3 (and earlier) and 16.4.2 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Technical Analysis

CVE-2022-38407 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe InCopy versions 17.3 and earlier, as well as 16.4.2 and earlier. This vulnerability allows an attacker to read memory outside the intended bounds, potentially leading to the disclosure of sensitive information stored in memory. Such information could include cryptographic keys, user credentials, or other sensitive data. The vulnerability can be exploited when a victim opens a specially crafted malicious file in Adobe InCopy, which triggers the out-of-bounds read. This attack vector requires user interaction, specifically the opening of a malicious file, which limits the attack surface to scenarios where the attacker can convince or trick the user into opening such a file. The out-of-bounds read can also be leveraged to bypass security mitigations like Address Space Layout Randomization (ASLR), which is designed to make exploitation more difficult by randomizing memory addresses. By leaking memory layout information, an attacker can more easily craft further exploits targeting the system. There are no known exploits in the wild at the time of this analysis, and no patches or updates have been linked in the provided information. The vulnerability is categorized as medium severity by the vendor, reflecting the moderate risk posed by the requirement for user interaction and the nature of the impact being information disclosure rather than direct code execution or system compromise.

Potential Impact

For European organizations, the impact of CVE-2022-38407 centers on potential leakage of sensitive information from systems running vulnerable versions of Adobe InCopy. Organizations in publishing, media, marketing, and other industries that rely on Adobe InCopy for collaborative editorial workflows are at particular risk. Disclosure of sensitive memory contents could lead to further targeted attacks, including privilege escalation or lateral movement within networks if the leaked data includes credentials or cryptographic material. The ability to bypass ASLR increases the likelihood that attackers could chain this vulnerability with others to achieve more severe outcomes. While the vulnerability does not allow remote code execution by itself, the requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files. This risk is heightened in environments where users frequently exchange InCopy files or where security awareness is low. The medium severity rating suggests that while the threat is not immediately critical, it should not be ignored, especially in sectors handling sensitive or regulated data. Failure to address this vulnerability could expose European organizations to data breaches, reputational damage, and potential regulatory penalties under frameworks such as GDPR if personal data is compromised.

Mitigation Recommendations

1. Immediate patching: Organizations should verify the version of Adobe InCopy in use and upgrade to the latest available version beyond 17.3 and 16.4.2, once Adobe releases a patch addressing this vulnerability. 2. File handling policies: Implement strict controls on the receipt and opening of InCopy files, especially from untrusted or external sources. Use sandboxing or isolated environments to open files when possible. 3. User training: Educate users about the risks of opening unsolicited or suspicious InCopy files and encourage verification of file sources before opening. 4. Network segmentation: Limit the ability of compromised endpoints to access sensitive internal systems to contain potential lateral movement. 5. Monitoring and detection: Deploy endpoint detection and response (EDR) tools to monitor for unusual file access patterns or memory disclosure attempts related to Adobe InCopy processes. 6. Application whitelisting: Restrict execution of unauthorized or unknown applications and scripts that could be used to deliver malicious files. 7. Incident response readiness: Prepare to investigate and respond to incidents involving Adobe InCopy exploitation, including forensic analysis of memory and file artifacts. These measures go beyond generic advice by focusing on controlling file handling workflows specific to Adobe InCopy and enhancing detection capabilities tailored to this vulnerability's exploitation method.
