CVE-2022-28819 is an out-of-bounds write vulnerability (CWE-787) affecting Adobe Character Animator versions 4.4.2 and earlier, as well as version 22.3 and earlier. This vulnerability arises when the software processes a specially crafted SVG file, leading to an out-of-bounds write condition in memory. Such a condition can corrupt memory and potentially allow an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically the victim opening a malicious SVG file, which is a common vector for social engineering attacks. The vulnerability does not require elevated privileges or prior authentication, but successful exploitation depends on tricking the user into opening the malicious file. No known exploits have been reported in the wild to date, and Adobe has not published official patches or mitigation details at the time of this analysis. The vulnerability impacts the confidentiality, integrity, and availability of the affected system by enabling arbitrary code execution, which could lead to data theft, system compromise, or disruption of services. Given the nature of the vulnerability, it is primarily a client-side risk affecting users who handle SVG files within Adobe Character Animator.

For European organizations, the impact of this vulnerability could be significant, especially for those in creative industries, media production, advertising, and digital content creation where Adobe Character Animator is commonly used. Successful exploitation could lead to unauthorized code execution, potentially resulting in data breaches, intellectual property theft, or disruption of creative workflows. Since the vulnerability requires user interaction, phishing or targeted social engineering campaigns could be used to deliver malicious SVG files. This risk is heightened in organizations with less mature cybersecurity awareness or insufficient email and file scanning controls. Additionally, compromised workstations could serve as footholds for lateral movement within corporate networks, increasing the risk of broader enterprise compromise. The vulnerability's impact on confidentiality and integrity is notable, as attackers could execute arbitrary code to exfiltrate sensitive data or manipulate content. Availability could also be affected if attackers deploy destructive payloads or ransomware. However, the requirement for user interaction and the absence of known exploits reduce the immediacy of the threat but do not eliminate the risk.

European organizations should implement targeted mitigations beyond generic advice: 1) Enforce strict email and file scanning policies to detect and block malicious SVG files, leveraging advanced threat protection solutions capable of deep file inspection. 2) Educate users specifically about the risks of opening unsolicited or unexpected SVG files, especially those received via email or messaging platforms. 3) Restrict the use of Adobe Character Animator to trusted users and environments, and consider sandboxing or application control policies to limit the execution context of the software. 4) Monitor and audit file access and application behavior for anomalies indicative of exploitation attempts. 5) Maintain up-to-date backups of critical creative assets to mitigate potential data loss from exploitation. 6) Engage with Adobe’s security advisories regularly to apply patches promptly once available. 7) Implement network segmentation to limit lateral movement if a workstation is compromised. These measures, combined with standard endpoint protection and intrusion detection, will reduce the likelihood and impact of exploitation.
