egg-compile.scm in CHICKEN 5.x before 5.3.1 allows arbitrary OS command execution during package installation via escape characters in a .egg file.
AnalysisAI
egg-compile.scm in CHICKEN 5.x before 5.3.1 allows arbitrary OS command execution during package installation via escape characters in a .egg file. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This OS Command Injection vulnerability could allow attackers to execute arbitrary operating system commands on the host.
Technical ContextAI
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. egg-compile.scm in CHICKEN 5.x before 5.3.1 allows arbitrary OS command execution during package installation via escape characters in a .egg file. Affected products include: Call-Cc Chicken. Version information: before 5.3.1.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
