versionscan

Versionscan is a tool for evaluating your currently installed PHP version and checking it against known CVEs and the versions they were fixed in to report back potential issues.

PLEASE NOTE: Work is still in progress to adapt the tool to linux distributions that backport security fixes. As of right now, this only reports back for the straight up version reported.

Installation

Using Composer

{
    "require": {
        "psecio/versionscan": "dev-master"
    }
}

The only current dependency is the Symfony console.

Usage

To run the scan against your current PHP version, use:

bin/versionscan

The script will check the PHP_VERSION for the current instance and generate the pass/fail results. The output looks similar to:

Executing against version: 5.4.24
+--------+---------------+------+------------------------------------------------------------------------------------------------------+
| Status | CVE ID        | Risk | Summary                                                                                              |
+--------+---------------+------+------------------------------------------------------------------------------------------------------+
| FAIL   | CVE-2014-3597 | 6.8  | Multiple buffer overflows in the php_parserr function in ext/standard/dns.c in PHP before 5.4.32 ... |
| FAIL   | CVE-2014-3587 | 4.3  | Integer overflow in the cdf_read_property_info function in cdf.c in file through 5.19, as used in... |

Results will be reported back colorized as well to easily show the pass/fail of the check.

Parameters

There are several parameters that can be given to the tool to configure its scans and results:

PHP Version

If you'd like to define a PHP version to check other than the one the script finds itself, you can use the php-version parameter:

bin/versionscan scan --php-version=4.3.2

Report Only Failures

You can also tell the versionscan to only report back the failures and not the passing tests:

bin/versionscan scan --fail-only

Sorting results

You can also sort the results either by the CVE ID or by severity (risk rating), with the sort parameter and either the "cve" or "risk" value:

bin/versionscan scan --sort=risk

Output formats

By default versionscan will output information directly to the console in a human-readable result. You can also specify other output formats that may be easier to parse programatically (like JSON). Use the --format option to change the output:

vendor/bin/versionscan scan --php-version=5.5 --format=json

Supported output formats are console, json, xml and html.

The HTML output format requires an --output option of the directory to write the file:

vendor/bin/versionscan scan --php-version=5.5 --format=html --output=/var/www/output

The result will be written to a file named something like versionscan-output-20150808.html

psecio / versionscan
