MediumApache HTTP Server fails to filter terminal escape sequences from error logs. Escape sequences are a series of characters that begin with the ASCII (0x1B) sequence and are followed by a series of arguments. If a remote attacker could inject escape sequences into an Apache error log, the attacker could take advantages of weaknesses in many terminal emulator software packages and launch further attacks against remote users. This could include denial of service attacks, file modification, data modification, and possibly the execution of arbitrary commands.
