Topic: zope vulnerability allows escalation of privileges Category: ports Module: zope Announced: 2001-01-15 Credits: Erik Enge Affects: Ports collection prior to the correction date. Corrected: 2000-12-20 Vendor status: Patch released FreeBSD only: NO I. Background zope is an object-based dynamic web application platform. II. Problem Description The zope port, versions prior to 2.2.4, contains a vulnerability due to the computation of local roles not climbing the correct hierarchy of folders, sometimes granting local roles inappropriately. This may allow users with privileges in one folder to gain the same privileges in another folder. The zope port is not installed by default, nor is it "part of FreeBSD" as such: it is part of the FreeBSD ports collection, which contains nearly 4500 third-party applications in a ready-to-install format. The ports collections shipped with FreeBSD 3.5.1 and 4.2 contain this problem since it was discovered after the releases. FreeBSD makes no claim about the security of these third-party applications, although an effort is underway to provide a security audit of the most security-critical ports. III. Impact Zope users with privileges in one folder may be able to gain the same privileges in other folders. If you have not chosen to install the zope port/package, then your system is not vulnerable to this problem. IV. Workaround Deinstall the zope port/package, if you have installed it. V. Solution One of the following: 1) Upgrade your entire ports collection and rebuild the zope port. 2) Deinstall the old package and install a new package dated after the correction date, obtained from: ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/www/zope-2.2.4.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/www/zope-2.2.4.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/www/zope-2.2.4.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/www/zope-2.2.4.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/www/zope-2.2.4.tgz 3) download a new port skeleton for the zope port from: http://www.freebsd.org/ports/ and use it to rebuild the port. 4) Use the portcheckout utility to automate option (3) above. The portcheckout port is available in /usr/ports/devel/portcheckout or the package can be obtained from: ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/devel/portcheckout-2.0.tgz - - -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (FreeBSD) Comment: For info see http://www.gnupg.org iQCVAwUBOmN6UVUuHi5z0oilAQGVdAP/TPreDK7sB21+F5wO6KAWKBZe4NZIRAlt aajsBSTmpCYGtQ1dbsIeMUtTYOzdR8FKO0CPYfZbl1cjGljW3HpWIus0ildznNeA LznyYR9fwoSNU0Vh9xtqZ3OolCGw+GY98Wg55RcgToDDxeNnT4ZSGZnf4zdwQw9S QbDfN6Br1oM= =c035 - - -----END PGP SIGNATURE----- - - --------------------------END INCLUDED TEXT-------------------- This security bulletin is provided as a service to AusCERT's members.
