Description

An Improper Validation of Syntactic Correctness of Input vulnerability in Intrusion Detection and Prevention (IDP) of Juniper Networks SRX Series and MX Series allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). Continued receipt of this specific packet will cause a sustained Denial of Service condition.

On all SRX Series and MX Series platforms, where IDP is enabled and a specific malformed SSL packet is received, the SSL detector crashes leading to an FPC core.

This issue affects Juniper Networks SRX Series and MX Series prior to SigPack 3598.

In order to identify the current SigPack version, following command can be used:

user@junos# show security idp security-package-version

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
