CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as problematic has been found in PHP (Programming Language Software). This affects the function parse_str. The manipulation of the argument one with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on integrity. The summary by CVE is:

The parse_str function in PHP 4.x up to 4.4.0 and 5.x up to 5.0.5, when called with only one parameter, allows remote attackers to enable the register_globals directive via inputs that cause a request to be terminated due to the memory_limit setting, which causes PHP to set an internal flag that enables register_globals and allows attackers to exploit vulnerabilities in PHP applications that would otherwise be protected.

The bug was discovered 10/31/2005. The weakness was shared 11/01/2005 by Stefan Esser with Hardened-PHP Project (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is uniquely identified as CVE-2005-3389 since 11/01/2005. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1059.007 according to MITRE ATT&CK.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.
