CVE-2021-44700 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Illustrator versions 25.4.2 and earlier, as well as 26.0.1 and earlier. This vulnerability arises when the software improperly handles memory boundaries while processing certain input files, leading to the reading of memory outside the intended buffer. Such out-of-bounds reads can result in the disclosure of sensitive memory contents, potentially exposing confidential information stored in memory. A notable aspect of this vulnerability is that it can be leveraged to bypass security mitigations such as Address Space Layout Randomization (ASLR), which is designed to prevent attackers from reliably predicting memory addresses. Exploitation requires user interaction, specifically that a victim opens a crafted malicious file in Adobe Illustrator. There are no known exploits in the wild at this time, and no official patches or updates have been linked in the provided information. The vulnerability was publicly disclosed in January 2022 and is classified with medium severity by the vendor. Since the vulnerability involves reading memory out-of-bounds without direct code execution or privilege escalation, the primary risk is information disclosure rather than system compromise. However, the ability to bypass ASLR could facilitate further exploitation chains if combined with other vulnerabilities. The affected product, Adobe Illustrator, is widely used in creative industries for vector graphics editing, making this vulnerability relevant to organizations involved in design, marketing, publishing, and related sectors.

For European organizations, the impact of CVE-2021-44700 centers on potential leakage of sensitive information from memory when malicious files are opened in Adobe Illustrator. This could include exposure of intellectual property, confidential design assets, or other sensitive data residing in application memory. The bypass of ASLR increases the risk that attackers could use this vulnerability as a stepping stone for more advanced exploits, potentially leading to privilege escalation or remote code execution if chained with other vulnerabilities. Organizations in sectors such as advertising, media, publishing, and manufacturing that rely heavily on Adobe Illustrator for design workflows are particularly at risk. The requirement for user interaction (opening a malicious file) means that targeted phishing or social engineering campaigns could be used to deliver the exploit. While no active exploitation has been reported, the presence of this vulnerability increases the attack surface and risk profile for affected organizations. Additionally, the lack of an official patch at the time of disclosure may prolong exposure. The confidentiality and integrity of sensitive design data could be compromised, potentially leading to intellectual property theft or reputational damage. Availability impact is minimal as the vulnerability does not cause denial of service or system crashes directly.

To mitigate CVE-2021-44700, European organizations should implement several specific measures beyond generic advice: 1) Restrict Adobe Illustrator file sources by enforcing strict policies on opening files only from trusted and verified origins to reduce the risk of malicious file delivery. 2) Employ advanced email filtering and sandboxing solutions to detect and block potentially malicious Illustrator files before they reach end users. 3) Educate users, especially designers and creative teams, about the risks of opening unsolicited or unexpected Illustrator files and encourage verification of file sources. 4) Monitor Adobe’s security advisories closely for the release of official patches or updates addressing this vulnerability and prioritize timely deployment once available. 5) Use endpoint detection and response (EDR) tools to monitor for unusual memory access patterns or attempts to bypass ASLR that could indicate exploitation attempts. 6) Implement application whitelisting and privilege restrictions to limit the ability of malicious files to execute or escalate privileges even if opened. 7) Consider isolating Adobe Illustrator usage to segmented network zones or virtualized environments to contain potential compromise. These targeted mitigations help reduce the likelihood of exploitation and limit the impact if exploitation occurs.
