CVE-2022-28279 is a use-after-free vulnerability (CWE-416) found in Adobe Photoshop versions 22.5.6 and earlier, as well as 23.2.2 and earlier. This vulnerability arises when Photoshop improperly manages memory, specifically freeing an object but continuing to use the pointer referencing that freed memory. An attacker can exploit this flaw by crafting a malicious file that, when opened by a victim in Photoshop, triggers the use-after-free condition. This can lead to arbitrary code execution within the context of the current user, allowing the attacker to execute malicious code with the same privileges as the user running Photoshop. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file, which is typical for file parsing vulnerabilities. There are no known exploits in the wild at the time of this analysis, and no official patches or updates are linked in the provided data, though Adobe typically addresses such vulnerabilities in security updates. The vulnerability affects widely used versions of Photoshop, a popular image editing software used by professionals and organizations globally. The technical root cause is improper memory management leading to use-after-free, which can cause memory corruption and enable code execution.

For European organizations, the impact of this vulnerability can be significant, especially for those in creative industries, media, advertising, and any sector relying heavily on Adobe Photoshop for digital content creation. Successful exploitation could lead to arbitrary code execution, potentially allowing attackers to install malware, steal sensitive data, or move laterally within a network under the compromised user's privileges. Since the vulnerability requires user interaction (opening a malicious file), phishing or social engineering campaigns could be used to deliver the exploit. This raises risks of targeted attacks against high-value individuals or departments. The compromise of Photoshop on workstations could serve as an entry point for broader network infiltration, data exfiltration, or ransomware deployment. Confidentiality and integrity of digital assets and intellectual property could be at risk. However, the impact is somewhat mitigated by the need for user interaction and the absence of known active exploits, reducing the immediacy of the threat but not eliminating it.

Organizations should prioritize updating Adobe Photoshop to the latest available version where this vulnerability is patched. Since no patch links are provided, monitoring Adobe's official security advisories for updates is critical. In the interim, implement strict email and file filtering to block or quarantine suspicious files, especially those with extensions commonly associated with Photoshop (e.g., PSD, PSB). Educate users on the risks of opening files from untrusted sources and implement policies restricting the opening of unsolicited or unexpected files. Employ endpoint protection solutions with behavior-based detection to identify suspicious activities related to memory corruption or code execution. Network segmentation can limit lateral movement if a workstation is compromised. Additionally, consider application whitelisting and sandboxing Photoshop processes where feasible to contain potential exploits. Regular backups and incident response plans should be maintained to recover from potential compromises.
