CVE-2022-35699 is an out-of-bounds write vulnerability (CWE-787) affecting Adobe Bridge versions 12.0.2 and earlier, as well as 11.1.3 and earlier. This vulnerability arises when Adobe Bridge improperly handles certain crafted files, leading to memory corruption through writing outside the intended buffer boundaries. Such memory corruption can be exploited by an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file using Adobe Bridge. The vulnerability does not require elevated privileges or prior authentication, but successful exploitation depends on tricking the user into opening the malicious file. 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 data. The vulnerability impacts confidentiality, integrity, and availability by enabling arbitrary code execution, potentially allowing attackers to install malware, steal data, or disrupt system operations. However, the attack vector is limited by the need for user interaction and the scope is constrained to the privileges of the current user running Adobe Bridge.

For European organizations, the impact of CVE-2022-35699 can be significant, particularly for those heavily reliant on Adobe Bridge for digital asset management, such as media companies, advertising agencies, and creative departments within enterprises. Successful exploitation could lead to unauthorized code execution, enabling attackers to deploy malware, exfiltrate sensitive intellectual property, or disrupt workflows. Since Adobe Bridge is often used on workstations with access to corporate networks and shared resources, compromise of a single endpoint could facilitate lateral movement within an organization. The requirement for user interaction reduces the risk of widespread automated exploitation but increases the likelihood of targeted attacks, such as spear-phishing campaigns delivering malicious files. Given the medium severity and absence of known exploits, the immediate risk is moderate, but organizations should not underestimate the potential for exploitation as threat actors often develop exploits for such vulnerabilities over time.

1. Immediate mitigation should focus on user awareness and training to recognize and avoid opening suspicious or unexpected files, especially those received via email or untrusted sources. 2. Implement strict email filtering and attachment scanning to block potentially malicious files before reaching end users. 3. Restrict the use of Adobe Bridge to trusted users and environments, and consider limiting file types that can be opened within the application through application whitelisting or sandboxing techniques. 4. Monitor endpoint behavior for unusual activities that may indicate exploitation attempts, such as unexpected process launches or network connections originating from Adobe Bridge. 5. Maintain up-to-date backups of critical data to enable recovery in case of compromise. 6. Regularly check for and apply official Adobe patches or updates addressing this vulnerability as soon as they become available, even though none are currently linked. 7. Employ endpoint detection and response (EDR) solutions capable of detecting memory corruption exploits and anomalous behaviors associated with arbitrary code execution.
