Description

Improper Input Validation vulnerability in Proxy component of Apache Pulsar allows an attacker to make TCP/IP connection attempts that originate from the Pulsar Proxy's IP address. When the Apache Pulsar Proxy component is used, it is possible to attempt to open TCP/IP connections to any IP address and port that the Pulsar Proxy can connect to. An attacker could use this as a way for DoS attacks that originate from the Pulsar Proxy's IP address. It hasn’t been detected that the Pulsar Proxy authentication can be bypassed. The attacker will have to have a valid token to a properly secured Pulsar Proxy. This issue affects Apache Pulsar Proxy versions 2.7.0 to 2.7.4; 2.8.0 to 2.8.2; 2.9.0 to 2.9.1; 2.6.4 and earlier.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v ≤ 2.6.42.6 and earlier ≤ v ≤ 2.6.42.7 ≤ v ≤ 2.7.42.7.0 ≤ v < 2.7.52.8 ≤ v ≤ 2.8.22.8.0 ≤ v < 2.8.32.9 ≤ v ≤ 2.9.12.9.0 ≤ v < 2.9.22.72.82.9
Affected range stops below 2.7.5, so it looks safe — our inference, not a vendor statement
Affected range stops below 2.8.3, so it looks safe — our inference, not a vendor statement
Affected range stops below 2.9.2, so it looks safe — our inference, not a vendor statement
