Description

A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system.

Affected configurations

• haxx curl (>= 7.0.0 <= 7.881) • fedoraproject fedora 36 • netapp active iq unified manager • netapp clustered data ontap 9.0 • netapp h300s firmware • netapp h500s firmware • netapp h700s firmware • netapp h410s firmware • splunk universal forwarder (>= 8.2.0 < 8.2.12) • splunk universal forwarder (>= 9.0.0 < 9.0.6) • splunk universal forwarder 9.1.0
