CVE-2023-21587 is a high-severity Heap-based Buffer Overflow vulnerability affecting Adobe InDesign versions 18.0 and 17.4. This vulnerability allows arbitrary code execution in the context of the current user. Exploitation of this vulnerability requires user interaction, as it necessitates that a victim opens a malicious file. With a CVSS score of 7.8, it presents significant risk to organizations using affected versions.
The potential impact of this vulnerability is extensive. Attackers may leverage this vulnerability to execute arbitrary code, thereby compromising the integrity and confidentiality of affected systems. Given the high severity rating, organizations should prioritize patching immediately to protect against possible exploitation.
Currently, there is no known public exploit or proof of concept available, but the risk associated with this vulnerability is substantial enough to warrant immediate action. Organizations utilizing any version of Adobe InDesign should assess their exposure and implement the necessary patches as soon as they are available.
Adobe has acknowledged this vulnerability and is expected to release updates. Security teams should monitor Adobe's advisories and apply updates as soon as they are available to mitigate risks associated with this vulnerability.
Vulnerability Details
This vulnerability allows arbitrary code execution due to a Heap-based Buffer Overflow in Adobe InDesign versions 18.0 and 17.4. The CVSS score for this vulnerability is 7.8, indicating a high level of severity. This vulnerability was published on January 13, 2023, and has been marked as modified.
The affected products include Adobe InDesign, and the vulnerability is classified under CWE-122. Organizations using these versions are strongly advised to implement remediation measures as soon as possible.
Technical Analysis
The root cause of the vulnerability stems from improper handling of heap memory. It allows attackers to potentially execute arbitrary code within the context of the current user. The attack vector is classified as local, meaning that an attacker must have access to the local machine. The attack complexity is low, and no privileges are required for exploitation, but user interaction is necessary.
Exploitation impacts confidentiality, integrity, and availability, all rated as high. Organizations should be aware that user interaction is required, which necessitates that a user opens a malicious file for the exploit to succeed.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to data, system integrity breaches, and service disruptions. The vulnerability's local exploitation requirement means that the blast radius may initially seem limited to users who open malicious files, but the impact could escalate if the exploit is used as a stepping stone for further attacks.
With a CVSS score of 7.8, this vulnerability falls into the high severity category, indicating a need for organizations to address it in their priority patch cycle. Security teams should monitor for updates and apply patches as soon as they become available to mitigate risks.
