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.
