Veritas Storage Foundation Arbitrary File Read Vulnerability
AFFECTED: Veritas Storage Foundation 5.0
PLATFORM: Solaris, Linux, AIX, HP-UX
CLASSIFICATION: Improper Ownership Management (CWE-282)
RESEARCHER: Derek Callaway
IMPACT: Arbitrary File Read
REFERENCES: CVE-2008-4638, SYM08-018, BID 31679
Veritas Storage Foundation 5.0 from Symantec provides a complete
solution for heterogeneous online storage management. Based on the
industry-leading Veritas Volume Manager and Veritas File System, it
provides a standard set of integrated tools to centrally manage
explosive data growth, maximize storage hardware investments, provide
data protection and adapt to changing business requirements.
VxFS is an extent based, journaling filesystem. It implements a
"Quick I/O for Databases" feature; qioadmin is the setuid root
administration utility for this functionality. When given an arbitrary
filename, it will write the file's contents to the standard error stream.
qioadmin will write arbitrary files (including /etc/shadow) to stderr.
Each line will be prepended with a custom error message followed by file
contents. Clearly, this can lead to privilege escalation by cracking the
password ciphertext for the "superuser" or root account.
Remove the set-uid bit from the qioadmin binary.
chmod u-s /opt/VRTS/bin/qioadmin
Symantec included a fix for this problem in the recent maintenance
release Veritas Software File System 5.0 MP3.
