A command injection vulnerability exists in IGEL OS versions prior to 11.04.270 within the Secure Terminal and Secure Shadow services. The flaw arises due to improper input sanitization in the handling of specially crafted PROXYCMD commands on TCP ports 30022 and 5900. An unauthenticated attacker with network access to a vulnerable device can inject arbitrary commands, leading to remote code execution with elevated privileges.

NOTE: IGEL OS v10.x has reached end-of-life (EOL) status.

An issue was discovered in the IGEL Universal Management Suite (UMS) 6.07.100. A hardcoded DES key in the PrefDBCredentials class allows an attacker, who has discovered encrypted superuser credentials, to decrypt those credentials using a static 8-byte DES key.

An issue was discovered in the IGEL Universal Management Suite (UMS) 6.07.100. The transmission of cleartext LDAP bind credentials by the cmdmgtloadmgttree command allows an attacker (who can intercept or inspect traffic between an authenticated UMS client and server) to compromise those LDAP bind credentials.

An issue was discovered in the IGEL Universal Management Suite (UMS) 6.07.100. A hardcoded DES key in the LDAPDesPWEncrypter class allows an attacker, who has discovered encrypted LDAP bind credentials, to decrypt those credentials using a static 8-byte DES key.

An issue was discovered in the IGEL Universal Management Suite (UMS) 6.07.100. Insecure permissions for the serverconfig registry key (under JavaSoft\Prefs\de\igel\rm\config in HKEYLOCALMACHINE\SOFTWARE) allow an unprivileged local attacker to read the encrypted dbuser and dbpassword values for the UMS superuser.

IGEL OS contains a use of a key past its expiration date vulnerability that allows for Secure Boot bypass. The igel-flash-driver module improperly verifies a cryptographic signature. Ultimately, a crafted root filesystem can be mounted from an unverified SquashFS image.
