CVE-2020-9715 is a critical memory corruption vulnerability affecting Adobe Acrobat and Reader that has been confirmed as exploited in the wild [1] [2].

Vulnerability Overview
  • Type: Use-After-Free (UAF) memory corruption vulnerability [3] [1].
  • Impact: Successful exploitation allows an attacker to execute arbitrary code on the target system [3] [1]. It can specifically enable the execution of malicious JavaScript and the running of malicious executable files within system memory [2].
Exploitation and Requirements
  • Method: The vulnerability is triggered when a user opens a specially crafted PDF document [3].
  • User Interaction: User interaction is required, as the victim must be convinced to open the malicious file [3].
  • Exploit Availability: Proof-of-concept (PoC) material and technical analysis regarding the exploitation of the Adobe `ESObject` (the component involved in the UAF) have been documented in security research, demonstrating how to manipulate the object cache to achieve code execution [2].
Exploitation in the Wild
  • Status: The vulnerability has been exploited in the wild, specifically targeting users running outdated versions of Adobe Acrobat and Reader [2].
  • CISA KEV: Due to its active exploitation, it is included in the Cybersecurity and Infrastructure Security Agency (CISA) Known Exploited Vulnerabilities (KEV) catalog, requiring organizations to prioritize its remediation [1].
Affected Versions and Mitigation
  • Affected Versions: The vulnerability affects several versions of Adobe Acrobat and Reader, including:
* Acrobat and Reader 2020.009.20074 and earlier * Acrobat and Reader 2020.001.30002 * Acrobat and Reader 2017.011.30171 and earlier * Acrobat and Reader 2015.006.30523 and earlier [1]
  • Mitigation: The primary mitigation is to ensure that Adobe Acrobat and Reader software is updated to the latest patched versions provided by Adobe. Organizations should consult the official Adobe security bulletins and CISA guidance for specific patch requirements [1].
