CVE-2022-30659 is an out-of-bounds write vulnerability (CWE-787) affecting Adobe InDesign versions 17.2.1 and earlier, as well as 16.4.1 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to write data outside the intended buffer limits. Such out-of-bounds writes can corrupt memory, potentially leading to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted InDesign file. Once opened, the crafted file triggers the vulnerability, enabling the attacker to execute code with the privileges of the user running InDesign. This could allow an attacker to install malware, steal data, or perform other malicious actions on the affected system. There are no known exploits in the wild at the time of this analysis, and no official patches or updates have been linked in the provided information. The vulnerability is classified as medium severity by Adobe, reflecting the requirement for user interaction and the limited scope of privilege escalation (restricted to the current user context). However, the risk remains significant for environments where users frequently open untrusted InDesign files or where InDesign is used in sensitive workflows.

For European organizations, the impact of CVE-2022-30659 can be considerable, especially in sectors relying heavily on Adobe InDesign for publishing, marketing, and design workflows, such as media companies, advertising agencies, and large enterprises with in-house creative teams. Successful exploitation could lead to unauthorized code execution, resulting in data theft, disruption of design workflows, or lateral movement within corporate networks if the compromised user account has elevated privileges. Given that the vulnerability requires user interaction, phishing or social engineering campaigns could be used to deliver malicious InDesign files. The confidentiality and integrity of sensitive design documents and intellectual property could be compromised. Additionally, if attackers leverage this vulnerability as an initial foothold, it could serve as a stepping stone for more extensive attacks targeting critical infrastructure or business operations. The medium severity rating suggests a moderate risk, but the actual impact depends on the organization's security posture, user awareness, and the sensitivity of the data handled via InDesign.

Organizations should implement several targeted mitigation strategies beyond generic patching advice: 1) Restrict the use of Adobe InDesign to trusted users and environments, limiting access to those who require it for their roles. 2) Implement strict file handling policies that block or quarantine InDesign files received from untrusted or external sources, especially via email or file-sharing platforms. 3) Employ advanced endpoint protection solutions capable of detecting anomalous behavior related to memory corruption or code execution attempts within Adobe InDesign processes. 4) Conduct user awareness training focused on the risks of opening unsolicited or suspicious design files, emphasizing the importance of verifying file sources. 5) Utilize application control or whitelisting to prevent unauthorized execution of code or scripts spawned by InDesign. 6) Monitor logs and network traffic for unusual activity originating from systems running InDesign, which could indicate exploitation attempts. 7) Stay informed about Adobe security advisories and apply patches promptly once available, as no patch links were provided at the time of this analysis. 8) Consider sandboxing or running InDesign in isolated environments where feasible to limit the impact of potential exploitation.
