CVE-2022-28224

16
FAUCET Score

CVE-2022-28224 describes a route hijacking vulnerability in Calico (versions 3.22.1 and below) and Calico Enterprise (versions 3.12.0 and below) when using the floating IP feature. A privileged attacker can exploit insufficient validation to set a floating IP annotation on a pod, even if the feature is disabled. This allows them to intercept and reroute network traffic to their compromised pod. The vulnerability has a CVSS score of 5.5 (Medium), indicating a network attack vector with low attack complexity, requiring high privileges, and potentially leading to high impact on availability and low impact on integrity. While the EPSS score is low, suggesting a low probability of exploitation, the FAUCET Risk Score is 27/100. Currently, there is no evidence of active exploitation, nor are there any public exploit codes available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are also minimal, suggesting it has not garnered significant attention.
