CVE-2022-28846 is an out-of-bounds write vulnerability (CWE-787) found in Adobe Bridge version 12.0.1 and earlier. Adobe Bridge is a digital asset management application widely used by creative professionals to organize, browse, and manage multimedia files. The vulnerability arises when the software improperly handles memory boundaries during file processing, allowing an attacker to write data outside the intended buffer. This memory corruption can lead to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file designed to trigger the out-of-bounds write. Successful exploitation could allow an attacker to execute code, potentially leading to unauthorized actions such as installing malware, stealing data, or further compromising the system. However, the attack vector is limited by the need for user action and the absence of known exploits in the wild as of the publication date. No official patches or updates have been linked, indicating that mitigation relies on user awareness and defensive controls until Adobe releases a fix.

For European organizations, especially those in creative industries such as media, advertising, and design that rely heavily on Adobe Bridge for asset management, this vulnerability poses a risk of localized compromise. An attacker exploiting this flaw could gain the same privileges as the user, potentially leading to data theft, unauthorized access to sensitive creative content, or lateral movement within corporate networks. While the vulnerability does not allow privilege escalation beyond the current user context, the risk is significant if the affected user has elevated permissions or access to critical systems. The requirement for user interaction reduces the likelihood of widespread automated attacks but increases the risk of targeted spear-phishing or social engineering campaigns. Additionally, the absence of known exploits in the wild suggests limited active exploitation, but the medium severity rating and the nature of the vulnerability warrant proactive measures. Organizations handling sensitive intellectual property or operating in regulated sectors must consider this vulnerability a potential vector for espionage or sabotage.

1. Implement strict user training and awareness programs focusing on the risks of opening files from untrusted or unknown sources, emphasizing the specific threat posed by malicious files targeting Adobe Bridge. 2. Employ application whitelisting and sandboxing techniques to restrict Adobe Bridge’s ability to execute arbitrary code or access sensitive system resources. 3. Use endpoint detection and response (EDR) solutions to monitor for unusual behaviors indicative of exploitation attempts, such as unexpected memory writes or process injections related to Adobe Bridge. 4. Enforce the principle of least privilege by ensuring users operate with minimal necessary permissions, limiting the potential impact of code execution within their context. 5. Regularly review and update software inventories to identify installations of Adobe Bridge and prioritize patching once Adobe releases an official update addressing CVE-2022-28846. 6. Consider network segmentation to isolate systems running Adobe Bridge from critical infrastructure to contain potential breaches. 7. Monitor threat intelligence feeds for any emerging exploit code or active campaigns targeting this vulnerability to adjust defenses accordingly.
