Name of the Vulnerable Software and Affected Versions Junos OS versions prior to 21.4R3-S6 Junos OS versions 22.2 prior to 22.2R3-S3 Junos OS versions 22.4 prior to 22.4R3 Junos OS Evolved versions prior to 21.4R3-S7-EVO Junos OS Evolved versions 22.2 prior to 22.2R3-S4-EVO Junos OS Evolved versions 22.4 prior to 22.4R3-EVO
Description The issue is related to an Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. This allows an unauthenticated, network-based attacker to cause an integrity impact to the downstream devices. When a peer sends a BGP update message containing the aggregator attribute with an ASN value of zero (0), rpd accepts and propagates this attribute, which can cause issues for downstream BGP peers receiving this.
Recommendations For Junos OS versions prior to 21.4R3-S6, update to version 21.4R3-S6 or later. For Junos OS versions 22.2 prior to 22.2R3-S3, update to version 22.2R3-S3 or later. For Junos OS versions 22.4 prior to 22.4R3, update to version 22.4R3 or later. For Junos OS Evolved versions prior to 21.4R3-S7-EVO, update to version 21.4R3-S7-EVO or later. For Junos OS Evolved versions 22.2 prior to 22.2R3-S4-EVO, update to version 22.2R3-S4-EVO or later. For Junos OS Evolved versions 22.4 prior to 22.4R3-EVO, update to version 22.4R3-EVO or later.
