CVE-2021-44185 is a security vulnerability identified in Adobe Bridge versions 11.1.2 and earlier, as well as version 12.0 and earlier. The vulnerability is classified as an out-of-bounds read (CWE-125), which occurs when the software reads data outside the boundaries of allocated memory buffers. This flaw can lead to the disclosure of sensitive memory contents, potentially exposing confidential information stored in memory. The vulnerability specifically affects the way Adobe Bridge processes RGB image files. An attacker can craft a malicious RGB file that, when opened by a user in Adobe Bridge, triggers the out-of-bounds read condition. This can allow the attacker to bypass memory protection mechanisms such as Address Space Layout Randomization (ASLR), which is designed to prevent exploitation of memory corruption vulnerabilities by randomizing memory addresses. Exploitation requires user interaction, as the victim must open the malicious RGB file within Adobe Bridge. There are no known public exploits in the wild at the time of this analysis, and Adobe has not provided explicit patch links in the provided data. The vulnerability primarily impacts confidentiality by potentially leaking sensitive memory data, but does not directly allow code execution or privilege escalation. The attack vector is local or via social engineering, relying on tricking users into opening malicious files. Given the nature of Adobe Bridge as a digital asset management tool widely used by creative professionals and enterprises for organizing media files, this vulnerability could be leveraged in targeted attacks to gather sensitive information from affected systems.

For European organizations, the impact of CVE-2021-44185 centers on the potential exposure of sensitive information residing in memory when users open malicious RGB files in Adobe Bridge. Organizations in sectors such as media, advertising, design, publishing, and any industry relying on digital asset management could be at risk. The confidentiality breach could lead to leakage of intellectual property, project files, or other sensitive data temporarily held in memory. While the vulnerability does not enable direct code execution or system compromise, the ability to bypass ASLR could facilitate further exploitation if chained with other vulnerabilities. This risk is heightened in environments where Adobe Bridge is integrated into workflows handling confidential or proprietary media assets. The requirement for user interaction limits large-scale automated exploitation but does not eliminate targeted spear-phishing or social engineering attacks. Additionally, the absence of known exploits in the wild suggests the threat is currently low to moderate but could escalate if exploit code becomes available. Disruption to availability or integrity is not expected from this vulnerability alone. Overall, the threat poses a moderate confidentiality risk that European organizations should address promptly to protect sensitive digital assets.

1. Update Adobe Bridge to the latest available version beyond 12.0, as vendors typically release patches for such vulnerabilities; if no patch is available, monitor Adobe advisories closely for updates. 2. Implement strict email and file attachment filtering to detect and block suspicious or malformed RGB files, reducing the risk of malicious files reaching end users. 3. Educate users, especially those in creative and media departments, about the risks of opening unsolicited or unexpected image files, emphasizing caution with RGB files from untrusted sources. 4. Employ application whitelisting and sandboxing techniques to isolate Adobe Bridge processes, limiting the potential impact of exploitation. 5. Use endpoint detection and response (EDR) tools to monitor for unusual memory access patterns or anomalous behavior in Adobe Bridge processes. 6. Enforce the principle of least privilege for users running Adobe Bridge to minimize the scope of data accessible in memory. 7. Regularly audit and inventory software versions across the organization to ensure vulnerable versions are identified and remediated promptly. 8. Consider disabling or restricting the handling of RGB files in Adobe Bridge if this functionality is not essential to business operations, as a temporary risk reduction measure.
