VectorAV:N/AC:L/Au:N/C:P/I:N/A:N
Name of the Vulnerable Software and Affected Versions Adobe Acrobat Reader DC versions 2021.005.20054 and earlier Adobe Acrobat Reader DC versions 2020.004.30005 and earlier Adobe Acrobat Reader DC versions 2017.011.30197 and earlier
Description The issue is related to a Type Confusion vulnerability that allows an unauthenticated attacker to read arbitrary system information in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file, potentially a specially crafted PDF file. This could enable an attacker to gain unauthorized access to protected information.
Recommendations For Adobe Acrobat Reader DC versions 2021.005.20054 and earlier, update to a version later than 2021.005.20054 to resolve the issue. For Adobe Acrobat Reader DC versions 2020.004.30005 and earlier, update to a version later than 2020.004.30005 to resolve the issue. For Adobe Acrobat Reader DC versions 2017.011.30197 and earlier, update to a version later than 2017.011.30197 to resolve the issue. As a temporary workaround, consider avoiding the use of getAnnots function until a patch is available. Restrict access to malicious PDF files to minimize the risk of exploitation.
