CVE-2022-30675 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 disclosing sensitive information from the process memory space. The flaw can be exploited by convincing a user to open a specially crafted malicious InDesign file. Successful exploitation could enable attackers to bypass security mitigations such as Address Space Layout Randomization (ASLR), which is designed to prevent reliable memory corruption exploits by randomizing memory addresses. Although the vulnerability does not directly allow code execution, the information disclosure could be leveraged as a stepping stone for further attacks, such as crafting more targeted exploits or leaking sensitive data. Exploitation requires user interaction, specifically opening a malicious file, and there are no known exploits in the wild as of the published date. Adobe has not provided patch links in the provided data, indicating that remediation may require updating to a fixed version once available or applying other mitigations. The vulnerability affects widely used versions of Adobe InDesign, a professional desktop publishing software commonly used in creative industries for layout design and publishing.

For European organizations, the impact of CVE-2022-30675 could be significant in sectors relying heavily on Adobe InDesign for document creation and publishing, such as media companies, advertising agencies, publishing houses, and corporate communications departments. The vulnerability could lead to unauthorized disclosure of sensitive information residing in memory, including potentially confidential document content, user credentials, or cryptographic keys if present in memory. This information leakage could facilitate further targeted attacks or intellectual property theft. While the vulnerability does not directly enable remote code execution, bypassing ASLR weakens the overall security posture and could be combined with other vulnerabilities for more severe exploitation. The requirement for user interaction limits the attack vector to social engineering or phishing campaigns distributing malicious InDesign files. Organizations with high volumes of document exchange or collaboration using InDesign files are at increased risk. Additionally, the lack of known exploits in the wild suggests a window of opportunity for proactive mitigation before active exploitation emerges.

European organizations should implement the following specific mitigations: 1) Enforce strict email and file attachment filtering policies to detect and block suspicious or unsolicited InDesign files, especially from unknown sources. 2) Educate users on the risks of opening files from untrusted origins and implement security awareness training focused on social engineering tactics involving document files. 3) Deploy endpoint protection solutions capable of detecting anomalous behavior related to Adobe InDesign processes, including memory access patterns indicative of exploitation attempts. 4) Monitor and restrict the use of outdated Adobe InDesign versions by maintaining an asset inventory and enforcing software update policies; prioritize upgrading to versions beyond 17.3 where the vulnerability is addressed. 5) Utilize application whitelisting and sandboxing techniques to limit the impact of malicious files and isolate InDesign processes from sensitive system components. 6) Implement network segmentation to reduce lateral movement if exploitation occurs. 7) Stay informed on Adobe security advisories for official patches or workarounds and apply them promptly once available.
