SAP » Sap Db : Security Vulnerabilities, CVEs, Published In 2004

The (1) instdbmsrv and (2) instlserver programs in SAP DB Development Tools 7.x trust the user-provided INSTROOT environment variable as a path when assigning setuid permissions to the lserver program, which allows local users to gain root privileges via a modified INSTROOT that points to a malicious dbmsrv or lserver program.

lserver in SAP DB 7.3 and earlier uses the current working directory to find and execute the lserversrv program, which allows local users to gain privileges with a malicious lserversrv that is called from a directory that has a symlink to the lserver program.
