CVE-2020-11733 is a critical vulnerability affecting Spirent TestCenter and Avalanche appliance admin interface firmware, specifically chassis versions 5.08 and earlier. An attacker with existing access to an SSH restricted shell, which is available via default credentials, can escalate privileges to root by exploiting shell metacharacters. This allows for full compromise of the appliance, including reading sensitive configuration files and potentially executing arbitrary code. The vulnerability has a CVSS score of 6.7 (Medium) due to its high impact on confidentiality, integrity, and availability, though it requires high privileges and local access. Currently, there is no public exploit code available, nor is there evidence of active exploitation or significant community discussion surrounding this CVE.
