CVE-2022-30676 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe InDesign versions 16.4.2 and earlier, as well as 17.3 and earlier. This vulnerability allows an attacker to read memory outside the intended buffer boundaries, potentially leading to the disclosure of sensitive information stored in memory. Such information could include cryptographic keys, user data, or other sensitive runtime information. The vulnerability can be exploited when a user opens a specially crafted malicious InDesign file, which triggers the out-of-bounds read condition. While this vulnerability does not directly allow code execution, it can be leveraged to bypass security mitigations such as Address Space Layout Randomization (ASLR), which randomizes memory addresses to prevent reliable exploitation of memory corruption bugs. By leaking memory layout information, an attacker can improve the chances of successful exploitation of other vulnerabilities. Exploitation requires user interaction, specifically opening a malicious file, which limits the attack vector to targeted phishing or social engineering campaigns. There are no known exploits in the wild reported at this time, and Adobe has not provided patch links in the provided data, indicating that remediation may still be pending or available through updates not referenced here. The vulnerability is classified as medium severity, reflecting its potential impact and exploitation complexity.

For European organizations, the impact of CVE-2022-30676 primarily involves the risk of sensitive information disclosure and the potential facilitation of further attacks by bypassing ASLR. Organizations heavily reliant on Adobe InDesign for publishing, marketing, or design workflows may be at risk if employees open malicious files. Sensitive memory disclosure could expose confidential project data, intellectual property, or user credentials stored in memory. While this vulnerability alone does not allow remote code execution, it can be a stepping stone for more severe attacks if combined with other vulnerabilities. The requirement for user interaction means that phishing or spear-phishing campaigns targeting European organizations could be a likely attack vector. This risk is heightened in sectors with high use of Adobe InDesign, such as media, advertising, publishing, and creative agencies. Additionally, organizations with strict data protection regulations (e.g., GDPR) must consider the implications of any data leakage resulting from exploitation. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

1. Apply the latest Adobe InDesign updates and patches as soon as they become available, even if not explicitly referenced here, to address this vulnerability. 2. Implement strict email and file attachment filtering to detect and block potentially malicious InDesign files, especially from untrusted sources. 3. Educate users on the risks of opening unsolicited or unexpected files, emphasizing caution with InDesign documents received via email or other channels. 4. Employ endpoint detection and response (EDR) solutions capable of monitoring and alerting on anomalous behavior related to Adobe InDesign processes. 5. Use application whitelisting to restrict execution of unauthorized or untrusted files within the environment. 6. Consider sandboxing or opening InDesign files in isolated environments to limit potential impact. 7. Monitor security advisories from Adobe and threat intelligence sources for updates on exploit availability or additional mitigations. 8. Review and enforce least privilege principles for users running Adobe InDesign to minimize potential damage from exploitation.
