The suite includes Exchange Online, \nSharePoint Online, Office Communications Online, Microsoft Forefront, and Microsoft Office Live Meeting. For businesses, \nthe Software-plus-Services approach enables organizations to access the capabilities of enterprise software through on-premises \nservers, as online services, or a combination of both, depending on specific business requirements. Services also provide the \noption to add complementary capabilities that enhance on-premises server software and simplify system management and maintenance. \n \n(Copy of the vendor Homepage: https://microsoftonline.com ) \n \n \nAbstract Advisory Information: \n============================== \nAn independent Vulnerability Laboratory Research Team discovered a client-side cross site scripting in flash component of Microsofts Website Application. \n \n \nVulnerability Disclosure Timeline: \n================================== \n2013-07-14: Researcher Notification & Coordination (Muhammad A.S.) \n2013-07-15: Vendor Notification (Microsoft Security Response Center - Security Program) \n2013-12-11: Vendor Response/Feedback (Microsoft Security Response Center - Security Program) \n2013-12-11: Vendor Fix/Patch (Microsoft Developer Team) \n2012-12-12: Public Disclosure (Vulnerability Laboratory) \n \n \nDiscovery Status: \n================= \nPublished \n \n \nAffected Product(s): \n==================== \nMicrosoft Corporation \nProduct: Photo Story - Flash 2013 Q2 \n \n \nExploitation Technique: \n======================= \nRemote \n \n \nSeverity Level: \n=============== \nMedium \n \n \nTechnical Details & Description: \n================================ \nAn independent vulnerability laboratory researcher discovered a client side input cross site in flash component of Microsofts Website Application. \nThe vulnerability allows remote attacker to execute malicious non-persistent script on client side. \n \nThe vulnerability is located in the flash photo-story module when processing the load 2 different manipulated xmlloc parameter via GET method. \nThe client-side script code will be executed in the flash web application layout as frame. During investigation it has been revealed \nthat a remote attacker can manipulate both entry points to inject his own html and java-script. \n \nExploitation of the vulnerability requires no privilege application user account but low or medium user interaction. \nSuccessful exploitation of the vulnerability results in session hijacking, persistent phishing, persistent malware injects, persistent external \nredirects and manipulation of affected module- or application context. \n \nVulnerable Module(s): \n[+] photo-story \n \nVulnerable File(s): \n[+] photostory3.swf \n \nVulnerable Parameter(s): \n[+] xmlloc \n \n \nProof of Concept (PoC): \n======================= \nThe client side cross site scripting vulnerability can be exploited by remote attacker with low privilege application \nuser account and low or medium required user interaction.
