CVE-2020-15148

78
FAUCET Score

CVE-2020-15148 is a critical remote code execution vulnerability affecting the Yii 2 framework prior to version 2.0.38, caused by the unsafe deserialization of untrusted user input. With a maximum CVSS score of 10.0, this flaw allows unauthenticated remote attackers to execute arbitrary commands with low complexity, potentially leading to a total compromise of the host system. While there are no reported Metasploit modules or CISA KEV listings, the availability of Nuclei scanning templates and a high EPSS score of 0.93 indicate a significant risk of automated exploitation, necessitating an immediate upgrade to the fixed version.
