ID CVE-2017-6621
Summary A vulnerability in the web interface of Cisco Prime Collaboration Provisioning could allow an unauthenticated, remote attacker to access sensitive data. The attacker could use this information to conduct additional reconnaissance attacks. The vulnerability is due to insufficient protection of sensitive data when responding to an HTTP request on the web interface. An attacker could exploit the vulnerability by sending a crafted HTTP request to the application to access specific system files. An exploit could allow the attacker to obtain sensitive information about the application which could include user credentials. This vulnerability affects Cisco Prime Collaboration Provisioning Software Releases 10.6 through 11.5. Cisco Bug IDs: CSCvc99626.

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.
nessus via4
description According to its self-reported version number, the remote Cisco Prime Collaboration Provisioning server is 9.x, 10.x, 11.x, or 12.x prior to 12.1. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists in the web interface when handling HTTP requests. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to disclose sensitive information about the application, such as user credentials. (CVE-2017-6621) - An authentication bypass vulnerability exists in the web interface due to missing security restraints in certain HTTP request methods that could allow accessing files. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request, to bypass authentication and execute arbitrary commands with root privileges. (CVE-2017-6622) - A flaw exists in the web interface that allows directory traversal outside of a restricted path due to improper validation of HTTP requests and a failure to apply role-based access controls (RBACs) to requested HTTP URLs. An authenticated, remote attacker can exploit this, via a specially crafted request that uses path traversal, to delete arbitrary files from the system. (CVE-2017-6635) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
