CVE-2022-23204 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Premiere Rush versions 2.0 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to read memory locations outside the intended buffer. Such out-of-bounds reads can lead to the disclosure of sensitive information stored in adjacent memory, which may include cryptographic keys, user data, or other confidential information. A critical aspect of this vulnerability is that it can be leveraged to bypass security mitigations like Address Space Layout Randomization (ASLR), which is designed to randomize memory addresses to prevent exploitation. By leaking memory layout information, an attacker can more easily craft further exploits against the system. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted file using Adobe Premiere Rush. There are no known exploits in the wild at the time of this report, and no patches have been linked or published yet. The vulnerability does not require elevated privileges or prior authentication, but it does depend on social engineering to convince the user to open the malicious file. Given the nature of Adobe Premiere Rush as a multimedia editing tool popular among content creators, the attack vector is primarily through crafted media files that could be distributed via email, file sharing, or compromised websites.

For European organizations, the impact of this vulnerability could be significant, especially for media companies, marketing agencies, and any enterprises relying on Adobe Premiere Rush for content creation. The disclosure of sensitive memory could lead to leakage of confidential project data, intellectual property, or user credentials if such information is present in memory. Additionally, by bypassing ASLR, attackers could use this vulnerability as a stepping stone for more advanced exploits, potentially leading to remote code execution or system compromise. This could result in data breaches, disruption of media production workflows, and reputational damage. The requirement for user interaction limits the scope somewhat, but targeted spear-phishing campaigns or supply chain attacks could increase risk. Organizations with strict data protection regulations, such as GDPR in Europe, could face compliance issues if sensitive data is exposed. Furthermore, the lack of available patches means that affected systems remain vulnerable until Adobe releases updates, increasing the window of exposure.

1. Implement strict email and file filtering to detect and block potentially malicious media files before they reach end users. 2. Educate users, especially those in creative roles, about the risks of opening files from untrusted sources and encourage verification of file origins. 3. Employ application whitelisting and sandboxing techniques to isolate Adobe Premiere Rush processes, limiting the impact of potential exploitation. 4. Monitor system and application logs for unusual behavior indicative of exploitation attempts, such as unexpected memory access patterns or crashes. 5. Use endpoint detection and response (EDR) tools capable of detecting anomalous memory reads or exploitation techniques targeting ASLR bypass. 6. Maintain up-to-date backups of critical project files to mitigate the impact of potential data loss or corruption. 7. Stay alert for official Adobe patches or advisories and prioritize their deployment once available. 8. Consider restricting the use of Adobe Premiere Rush to trusted users or environments until a patch is released.
