CVE-2021-36000 is a memory corruption vulnerability classified under CWE-788 (Access of Memory Location After End of Buffer) affecting Adobe Character Animator version 4.2 and earlier. The vulnerability arises when the software parses a specially crafted file, leading to out-of-bounds memory access. This memory corruption can be exploited by an unauthenticated attacker to execute arbitrary code within the context of the current user. However, exploitation requires user interaction, specifically the victim opening a maliciously crafted file. The vulnerability impacts the confidentiality, integrity, and availability of the affected system by potentially allowing arbitrary code execution, which could lead to unauthorized data access, modification, or system compromise. No public exploits have been reported in the wild, and no official patches or updates are referenced in the provided information. The attack vector is local in the sense that the attacker must convince the user to open a malicious file, making social engineering or phishing a likely delivery method. Given that Adobe Character Animator is a specialized animation software used primarily by creative professionals, the scope of affected systems is somewhat limited to organizations and individuals using this product. The vulnerability does not require authentication but does require user interaction, which reduces the ease of exploitation compared to fully remote vulnerabilities. The lack of a CVSS score necessitates an independent severity assessment based on the technical details and impact potential.

For European organizations, the impact of CVE-2021-36000 depends largely on the extent of Adobe Character Animator deployment within creative industries such as media, advertising, and digital content production. Successful exploitation could lead to arbitrary code execution, enabling attackers to steal sensitive intellectual property, disrupt creative workflows, or use compromised systems as footholds for lateral movement within corporate networks. Confidentiality could be compromised through unauthorized access to proprietary animation projects, while integrity could be affected by unauthorized modification of files or software behavior. Availability risks include potential system crashes or denial of service caused by memory corruption. Although the requirement for user interaction limits mass exploitation, targeted attacks against high-value creative teams or agencies remain a concern. Additionally, compromised systems could be leveraged to distribute malware or ransomware within organizations. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as threat actors often develop exploits post-disclosure. European organizations with significant creative departments or those involved in digital media production should consider this vulnerability a moderate risk that warrants timely mitigation.

1. Immediate mitigation involves educating users, particularly those in creative roles, about the risks of opening files from untrusted sources and implementing strict email and file-sharing policies to reduce exposure to malicious files. 2. Since no official patches are referenced, organizations should monitor Adobe’s security advisories closely and apply updates as soon as they become available. 3. Employ application whitelisting and sandboxing techniques for Adobe Character Animator to limit the impact of potential exploitation. 4. Use endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unexpected process spawning or memory access violations. 5. Restrict user privileges to the minimum necessary to reduce the impact of arbitrary code execution. 6. Implement network segmentation to isolate creative workstations from critical infrastructure, limiting lateral movement if compromise occurs. 7. Regularly back up critical project files and maintain version control to recover from potential data corruption or ransomware attacks stemming from exploitation. 8. Conduct phishing awareness training tailored to creative teams to reduce the likelihood of users opening malicious files.
