Message-ID: <04F9AFDCA6560B42B91DB1A429B7D0DE05532DCF@G1W3778.americas.hpqcorp.net> Date: Wed, 22 Aug 2012 15:42:56 +0000 From: ZDI Disclosures <zdi-disclosures@...pingpoint.com> To: "'full-disclosure@...ts.grok.org.uk'" <full-disclosure@...ts.grok.org.uk>, "'bugtraq@...urityfocus.com'" <bugtraq@...urityfocus.com> Cc: ZDI Disclosures <zdi-disclosures@...com> Subject: ZDI-12-146 : Novell eDirectory RelativeToFullDN Parsing Remote Code Execution Vulnerability -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-146 : Novell eDirectory RelativeToFullDN Parsing Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-146 August 22, 2012 - -- CVE ID: - -- CVSS: 10, AV:N/AC:L/Au:N/C:C/I:C/A:C - -- Affected Vendors: Novell - -- Affected Products: Novell eDirectory - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12472. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell eDirectory. Authentication is not required to exploit this vulnerability. The specific flaw exists within how the service handles a specially formatted LDAP request. When handling a particular set of commands, the server will copy a string described in the packet into a statically sized buffer without validating it's length. This leads to a stack-based overflow and as such can be exploited to achieve code execution under the context of the application. - -- Vendor Response: Novell has issued an update to correct this vulnerability. More details can be found at: http://www.novell.com/support/kb/doc.php?id=7009947 - -- Disclosure Timeline: 2011-10-28 - Vulnerability reported to vendor 2012-08-22 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities. Researchers interested in getting paid for their security research through the ZDI can find more information and sign-up at: http://www.zerodayinitiative.com The ZDI is unique in how the acquired vulnerability information is used.
