CVE-2020-9585

Vulnerability

Description

CVE-2020-9585 is a defense-in-depth security mitigation vulnerability affecting multiple Magento versions, including Adobe Commerce and Magento Open Source [1]. The exact root cause is not publicly detailed, but the vulnerability arises from a weakness in the security mitigations intended to protect against other attack vectors.

Attack

Vector

The official description does not specify the attack vector or prerequisites for exploitation. However, as a defense-in-depth bypass, it likely requires an attacker to have already achieved some level of access, such as administrative credentials or the ability to execute other exploits. The vulnerability is classified with high severity, indicating that exploitation could be accomplished with low complexity and without user interaction.

Impact

Successful exploitation could allow an attacker to execute arbitrary code on the affected system, potentially leading to complete compromise of the Magento instance and associated data [1].

Mitigation

Given the version ranges (e.g., 2.3.4 and earlier), versions later than these boundaries are likely patched. Users should upgrade to the latest available releases of Adobe Commerce or Magento Open Source to mitigate the risk.
