This security bulletin contains information about 3 vulnerabilities.
1) Command injection (CVE-ID: CVE-2018-14354)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to command injection. A remote attacker can use IMAP servers to inject and execute arbitrary commands via backquote characters, related to the mailboxes command associated with a manual subscription or unsubscription.
2) Command injection (CVE-ID: CVE-2018-14357)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to command injection. A remote attacker can use IMAP servers to inject and execute arbitrary commands via backquote characters, related to the mailboxes command associated with an automatic subscription.
3) Path traversal (CVE-ID: CVE-2018-14362)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information cause DoS condition on the target system.
The vulnerability exists due to forbid characters that may have unsafe interaction with message-cache pathnames, as demonstrated by a '/' character. A remote attacker can conduct directory traversal attack and gain access to arbitrary data or cause the service to crash.
