Description
The issue is related to insufficient input validation, which can be exploited by a remote attacker to execute arbitrary code. An unauthenticated attacker could leverage this vulnerability to obtain NTLMv2 credentials. Exploitation requires user interaction, such as opening a maliciously crafted Microsoft Office file or visiting an attacker-controlled web page.
Recommendations
For Adobe Acrobat Reader versions 23.003.20244 and earlier, update to a version later than 23.003.20244 to resolve the issue.
For Adobe Acrobat Reader versions 20.005.30467 and earlier, update to a version later than 20.005.30467 to resolve the issue.
For Adobe Acrobat 2020, consider disabling the ability to open maliciously crafted Microsoft Office files until a patch is available.
For Adobe Acrobat Document Cloud, restrict access to untrusted web pages to minimize the risk of exploitation.
As a temporary workaround, consider avoiding the use of NTLMv2 credentials in sensitive operations until the issue is resolved.
