CVE-2026-0244: CWE-295 Improper Certificate Validation in Palo Alto Networks Prisma SD-WAN ION
An improper certificate validation vulnerability in the Palo Alto Networks Prisma SD-WAN ION enables man-in-the-middle (MitM) attacker to impersonate the controller.
AI Analysis
Technical Summary
This vulnerability in Prisma SD-WAN ION arises from improper certificate validation, which can be exploited by an attacker positioned to intercept communications to impersonate the controller. The affected versions are 6.3.0, 6.4.0, and 6.5.0. The CVSS 4.0 vector indicates the attack requires adjacent network access, no privileges, and no user interaction, with partial impact on confidentiality, integrity, and availability. The vulnerability is classified under CWE-295, indicating a failure to properly validate certificates, which is critical for secure communications.
Potential Impact
Successful exploitation allows a man-in-the-middle attacker to impersonate the Prisma SD-WAN ION controller, potentially leading to interception or manipulation of network traffic. This could compromise the confidentiality and integrity of communications between the controller and devices. However, the attack requires adjacent network access and no known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the Palo Alto Networks vendor advisory for current remediation guidance. Until an official fix is released, organizations should monitor vendor communications for updates. No specific temporary mitigations are provided in the available data.
