Severity:	low
Title:	ViewCVS: Information leak and XSS vulnerabilities
Date:	12/28/2004
Bugs:	#72461, #73772
ID:	200412-26

Synopsis

ViewCVS is vulnerable to an information leak and to cross-site scripting (XSS) issues.

Background

ViewCVS is a browser interface for viewing CVS and Subversion version control repositories through a web browser.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-apps/viewcvs	<= 0.9.2_p20041207	>= 0.9.2_p20041207-r1	All supported architectures

Description

The tar export functions in ViewCVS bypass the 'hide_cvsroot' and 'forbidden' settings and therefore expose information that should be kept secret (CAN-2004-0915). Furthermore, some error messages in ViewCVS do not filter user-provided information, making it vulnerable to a cross-site scripting attack (CAN-2004-1062).

Impact

By using the tar export functions, a remote attacker could access information that is configured as restricted. Through the use of a malicious request, an attacker could also inject and execute malicious script code, potentially compromising another user's browser.

Workaround

There is no known workaround at this time.

Resolution

All ViewCVS users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/viewcvs-0.9.2_p20041207-r1"
