Sco Santa Cruz Operation (SCO) OpenServer 5.0.5

Buffer overflow in login in various System V based operating systems allows remote attackers to execute arbitrary commands via a large number of arguments through services such as telnet and rlogin.

Buffer overflows in wuarchive ftpd (wu-ftpd) and ProFTPD lead to remote root access, a.k.a. palmetto.

Buffer overflow in termsh on SCO OpenServer 5.0.7 allows remote attackers to execute arbitrary code via a long -o command line argument. NOTE: this is probably a different vulnerability than CVE-2005-0351 since it involves a distinct attack vector.

SCO OpenServer 5.0.5 through 5.0.7 only supports Xauthority style access control when users log in using scologin, which allows remote attackers to gain unauthorized access to an X session via other X login methods.

Buffer overflow in MMDF server allows remote attackers to gain privileges via a long MAIL FROM command to the SMTP daemon.

Buffer overflow in sar for SCO OpenServer 5.0.0 through 5.0.5 may allow local users to gain root privileges via a long -f parameter, a different vulnerability than CVE-1999-1570.

SCO Internet Manager (mana) allows local users to execute arbitrary programs by setting the REMOTE_ADDR environment variable to cause menu.mana to run as if it were called from ncsa_httpd, then modifying the PATH environment variable to point to a malicious "hostname" program.

The scosession program in OpenServer 5.0.6 and 5.0.7 allows local users to gain privileges via crafted strings on the commandline.

Format string vulnerability in crontab for SCO OpenServer 5.0.5 and 5.0.6 allows local users to gain privileges via format string specifiers in the file name argument.

SCO Doctor allows local users to gain root privileges through a Tools option.

The getdbm procedure in ypxfrd allows local users to read arbitrary files, and remote attackers to read databases outside /var/yp, via a directory traversal and symlink attack on the domain and map arguments.

Inetd in OpenServer 5.0.5 allows remote attackers to cause a denial of service (crash) via a port scan, e.g. with nmap -PO.

Buffer overflow in lpstat in SCO OpenServer 5.0 through 5.0.6a allows local users to execute arbitrary code as group bin via a long command line argument.

vi as included with SCO OpenServer 5.0 - 5.0.6 allows a local attacker to overwrite arbitrary files via a symlink attack.

snmpd in SCO OpenServer has an SNMP community string that is writable by default, which allows local attackers to modify the host's configuration.

Certain scripts in OpenServer before 5.0.6 allow local users to overwrite files and conduct other unauthorized activities via a symlink attack on temporary files.
