Directory traversal vulnerability in edit.php in pheap allows remote attackers to read and modify arbitrary files via a .. (dot dot) in the filename parameter.
This using slashes and url encoding combined to bypass validation logic vulnerability has been classified with a high base score of 9.4, a high impact score of 9.2 and a high exploitability score of 10.
The economic impact provides a custom overview of the affected areas by this vulnerability. If there is a higher amount of predicted attacks, there is a higher probability to be affected by this vulnerability in this particular region.
Common Attack Pattern Enumeration and Classification (CAPEC) is a comprehensive dictionary and classification taxonomy of known attacks that can be used by analysts, developers, testers, and educators to deepen community understanding and enhance protection. The vulnerability has been classificated in 8 categories.
Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
Using Slashes and URL Encoding Combined to Bypass Validation Logic
This attack targets the encoding of the URL combined with the encoding of the slash characters. An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL
Using Escaped Slashes in Alternate Encoding
This attack targets the use of the backslash in alternate encoding. An attacker can provide a backslash as a leading character and causes a parser to believe that the next character is special
An adversary uses path manipulation methods to exploit insufficient input validation of a target to obtain access to data that should be not be retrievable by ordinary well-formed requests. A typical variety of this attack involves specifying a path to a desired file together with dot-dot-slash characters, resulting in the file access API or function traversing out of the intended directory structure and into the root file system
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
CPE is a structured naming scheme for information technology systems, software, and packages. Based on a common Uniform Resource Identifier (URI) syntax, CPE includes a formal naming format, a method for validating system names, and a description format for attaching text and tests to the name.
