Description

Adobe InDesign versions 17.2.1 (and earlier) and 16.4.1 (and earlier) are affected by an Out-Of-Bounds Write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Technical Analysis

CVE-2022-34247 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 during processing of certain input data, leading to the possibility of writing data outside the allocated buffer. Such out-of-bounds writes can corrupt memory, potentially allowing an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically the opening of a maliciously crafted InDesign file. The vulnerability does not require elevated privileges or authentication but depends on tricking a user into opening a compromised file, which could be delivered via email, file sharing, or other means. No known public exploits have been reported in the wild to date, and Adobe has not published a patch link in the provided data, indicating that remediation may still be pending or available through updates not referenced here. The vulnerability impacts confidentiality, integrity, and availability by enabling arbitrary code execution, which could lead to data theft, system compromise, or denial of service. Given the nature of InDesign as a professional desktop publishing tool, the attack surface is primarily users who handle document creation and design, often in creative industries, marketing, publishing, and corporate communications.

Potential Impact

For European organizations, the impact of this vulnerability can be significant, especially for those in sectors relying heavily on Adobe InDesign for document production, such as media, publishing houses, advertising agencies, and corporate marketing departments. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to data breaches, intellectual property theft, or lateral movement within corporate networks. This could disrupt business operations and damage reputations. Since the vulnerability requires user interaction, phishing or social engineering campaigns targeting European employees could be an effective attack vector. Additionally, organizations with less mature cybersecurity awareness or lacking robust email filtering and endpoint protection may be more vulnerable. The impact is compounded in environments where InDesign is used on systems with access to sensitive data or critical infrastructure. However, the medium severity rating and lack of known exploits suggest the threat is moderate but should not be underestimated given the potential for targeted attacks.

Mitigation Recommendations

Organizations should implement the following specific mitigations: 1) Ensure all Adobe InDesign installations are updated to the latest available version beyond 17.2.1 and 16.4.1, as Adobe typically releases patches for such vulnerabilities; if no official patch is available, consider applying vendor-recommended workarounds or disabling InDesign usage temporarily in high-risk environments. 2) Educate users on the risks of opening unsolicited or suspicious InDesign files, emphasizing verification of file sources before opening. 3) Deploy advanced email filtering solutions capable of scanning and quarantining potentially malicious attachments, including InDesign files. 4) Utilize endpoint detection and response (EDR) tools to monitor for anomalous behaviors indicative of exploitation attempts, such as unexpected memory writes or process injections related to InDesign. 5) Implement application whitelisting to restrict execution of unauthorized files and scripts. 6) Segment networks to limit the lateral movement potential if a system is compromised. 7) Regularly back up critical data to enable recovery in case of compromise. These steps go beyond generic advice by focusing on user behavior, detection capabilities, and network architecture adjustments tailored to the nature of this vulnerability.
