CVE-2025-64896 is a vulnerability classified under CWE-379, which pertains to the creation of temporary files in directories with incorrect permissions. Specifically, Adobe Creative Cloud Desktop versions 6.4.0.361 and earlier improperly handle temporary file creation, allowing an attacker to manipulate these files to disrupt the application's normal operation, resulting in a denial-of-service (DoS) condition. The vulnerability requires user interaction, meaning the victim must open a maliciously crafted file to trigger the exploit. The attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The scope remains unchanged (S:U), and the impact affects availability only (A:H), with no impact on confidentiality or integrity. This vulnerability could be leveraged by attackers to interrupt workflows dependent on Adobe Creative Cloud Desktop, potentially causing downtime or loss of productivity. No known exploits have been reported in the wild, and no official patches have been released at the time of this report. The lack of confidentiality and integrity impact reduces the risk of data breaches, but the availability impact can be significant for organizations relying on this software for creative and design tasks. The vulnerability highlights the importance of secure temporary file handling and proper permission settings to prevent exploitation.

For European organizations, the primary impact of CVE-2025-64896 is operational disruption due to denial-of-service conditions affecting Adobe Creative Cloud Desktop. Industries such as media, advertising, design, and digital content creation, which heavily rely on Adobe Creative Cloud, may experience workflow interruptions, leading to productivity losses and potential project delays. Although the vulnerability does not compromise data confidentiality or integrity, the availability impact can affect service delivery and client commitments. Organizations with large creative teams or those providing digital services may face increased risk. Additionally, the requirement for user interaction means that social engineering or phishing campaigns could be used to trick users into opening malicious files, increasing the attack surface. The absence of known exploits in the wild currently limits immediate risk, but the vulnerability remains a concern until patched. Failure to address this issue could also expose organizations to targeted attacks aiming to disrupt operations during critical periods.

To mitigate CVE-2025-64896, organizations should implement several specific measures beyond generic advice: 1) Enforce strict file system permissions on directories used for temporary file creation by Adobe Creative Cloud Desktop to prevent unauthorized manipulation. 2) Monitor and audit temporary file creation and access patterns for anomalies that could indicate exploitation attempts. 3) Educate users about the risks of opening files from untrusted sources and implement robust email filtering and attachment scanning to reduce malicious file delivery. 4) Use application whitelisting and sandboxing techniques to limit the impact of potentially malicious files. 5) Deploy endpoint detection and response (EDR) solutions capable of detecting suspicious file operations related to temporary files. 6) Maintain up-to-date backups of critical work to minimize disruption in case of DoS conditions. 7) Once Adobe releases an official patch, prioritize its deployment across all affected systems. 8) Consider restricting or controlling the use of Adobe Creative Cloud Desktop in high-risk environments until the vulnerability is addressed.
