CVE-2022-30672 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 data that helps bypass security mitigations like Address Space Layout Randomization (ASLR), which is designed to prevent exploitation of memory corruption vulnerabilities by randomizing memory addresses. The exploitation vector requires user interaction, specifically that a victim opens a maliciously crafted InDesign file. There are no known exploits in the wild at this time, and Adobe has not provided patch links in the provided data, indicating that remediation may still be pending or not publicly disclosed. The vulnerability does not inherently allow code execution but can be leveraged as a stepping stone in a more complex attack chain by leaking memory contents that aid further exploitation. Since the vulnerability involves reading out-of-bounds memory, it primarily impacts confidentiality by exposing sensitive data. The requirement for user interaction and the absence of remote code execution reduce the immediate risk, but the vulnerability remains significant due to the potential for information disclosure and subsequent attack escalation.

For European organizations, the impact of CVE-2022-30672 centers on confidentiality breaches and potential escalation of attacks against systems running Adobe InDesign. Organizations in sectors such as publishing, media, design, and advertising, which commonly use InDesign, could be targeted to leak sensitive intellectual property or internal documents. Disclosure of memory contents could also reveal cryptographic keys, credentials, or other sensitive data, enabling attackers to bypass security controls like ASLR and potentially execute further exploits. This could lead to data breaches, loss of proprietary information, and reputational damage. Since exploitation requires user interaction, phishing or social engineering campaigns distributing malicious InDesign files are likely attack vectors. The medium severity rating suggests moderate risk, but the threat could be more pronounced in environments where InDesign is widely used and where sensitive data is handled. Additionally, organizations with less mature security awareness or lacking robust email/file scanning defenses may be more vulnerable. The absence of known exploits in the wild reduces immediate urgency but does not eliminate risk, especially as attackers may develop exploits over time.

1. Apply patches promptly once Adobe releases official updates addressing CVE-2022-30672. Monitor Adobe security advisories closely. 2. Implement strict email and file scanning policies to detect and block malicious InDesign files, including sandboxing unknown attachments. 3. Educate users about the risks of opening unsolicited or unexpected InDesign files, emphasizing caution with files from unknown or untrusted sources. 4. Employ application whitelisting to restrict execution of unauthorized files and scripts. 5. Use endpoint detection and response (EDR) solutions to monitor for suspicious activity related to Adobe InDesign processes. 6. Restrict InDesign usage to necessary personnel and consider network segmentation to limit exposure. 7. Regularly back up critical data and maintain incident response plans to quickly address potential breaches. 8. Consider disabling or limiting features in InDesign that handle external file imports if feasible. These targeted mitigations go beyond generic advice by focusing on user interaction vectors, file handling policies, and monitoring specific to Adobe InDesign environments.
