Detailsinfo

A vulnerability classified as critical has been found in Spirent Avalanche up to 5.08. Affected is an unknown function of the component Admin Interface. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered on Spirent TestCenter and Avalanche appliance admin interface firmware. An attacker, who already has access to an SSH restricted shell, can achieve root access via shell metacharacters. The attacker can then, for example, read sensitive files such as appliance admin configuration source code. This affects Spirent TestCenter and Avalanche products which chassis version <= 5.08. The SSH restricted shell is available with default credentials.

The weakness was shared 08/13/2020. This vulnerability is traded as CVE-2020-11733 since 04/13/2020. It is possible to launch the attack remotely. The successful exploitation requires a authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1055 by the MITRE ATT&CK project.
