Adobe Photoshop versions 23.5.5 (and earlier) and 24.7 (and earlier) are affected by an Access of Uninitialized Pointer vulnerability that could result in arbitrary code execution in the context of the current user. This vulnerability allows exploitation through user interaction, as the victim must open a malicious file for the attack to succeed. With a CVSS score of 7.8, this high-severity vulnerability poses a significant risk to organizations, necessitating prompt action to mitigate potential threats.
Risk to organizations includes unauthorized access and execution of harmful code, which could lead to data breaches or system compromise. Given the requirement for user interaction, the risk is elevated in environments where users may inadvertently open malicious files. Therefore, organizations should prioritize patching immediately to safeguard their systems against this vulnerability.
As of now, there are no confirmed public exploits available in the wild. However, the nature of this vulnerability warrants a proactive approach to security, ensuring that users are aware of the risks associated with opening untrusted files. Organizations that utilize Adobe Photoshop should take immediate steps to update their software to the latest versions to mitigate this vulnerability.
This vulnerability's disclosure on October 11, 2023, marks an important point for security teams to assess their defenses. Organizations should implement robust user training and awareness programs to reduce the likelihood of exploitation through social engineering tactics.
In summary, Adobe Photoshop users should act swiftly to update their applications and reinforce their security practices to mitigate the risks associated with CVE-2023-26370.
Vulnerability Details
Adobe Photoshop versions 23.5.5 (and earlier) and 24.7 (and earlier) are affected by an Access of Uninitialized Pointer vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. The vulnerability is classified under CWE-824.
The CVSS score for this vulnerability is 7.8, indicating a high severity level due to the potential for significant impact on confidentiality, integrity, and availability. The vulnerability primarily affects local installations of Adobe Photoshop and requires no privileges for exploitation, but it does necessitate user interaction.
The affected products include Photoshop 2022, 2023, and 2024 versions, with the vulnerability existing in all versions prior to vendor patch. Adobe has acknowledged the importance of addressing this vulnerability promptly.
Technical Analysis
The root cause of this vulnerability lies in the handling of uninitialized pointers, which can lead to arbitrary code execution. The attack vector is local, meaning that an attacker must have physical or logical access to the user's machine to exploit this vulnerability effectively. The attack complexity is rated as low, as it does not require advanced knowledge or skills to execute.
No privileges are required for the exploitation of this vulnerability, making it particularly dangerous. User interaction is necessary, as the malicious file must be opened by the victim, creating an opportunity for attackers to leverage social engineering tactics.
The vulnerability has high impacts on confidentiality, integrity, and availability, potentially allowing attackers to access sensitive data, modify files, or disrupt service.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is substantial, especially for organizations that utilize Adobe Photoshop for critical operations. The potential for unauthorized access and arbitrary code execution poses a significant threat, particularly in environments where users may be targeted by phishing attempts or other social engineering techniques.
Organizations must assess the potential blast radius of this vulnerability, considering the data sensitivity and functionality of systems using Adobe Photoshop. The urgency assessment is high, as the CVSS score indicates a severe threat that could lead to serious consequences if exploited.
Given that exploitation requires user interaction, organizations should focus on enhancing user awareness and implementing strict policies regarding file handling and software updates to minimize risk exposure.
