Summary

The handle_request function in lib/HTTPServer.pm in Monitorix before 3.3.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the URI.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.
  • 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.

      - Added a complete statistical Memcached graph. [#27]
    
        - Added support for different BIND stats versions (2 and
          3 right now). (thanks to Ivo Brhel, ivb AT volny.cz)
    
      - Added two new alerts in the 'disk' graph in order to
        know if a disk drive has exceeded or reached a threshold
        for reallocated and pending sectors. (suggested by
        Matthew Connelly, maff AT maff.im)
    
      - Added a new option called 'max_historic_years' (with a
        default value of 1), which enables the ability to have
        up to 5 years of data. Beware with this option because
        it generates a new '.rrd' file every time the value is
        extended, losing the current historical data. (suggested
        by Mohan Reddy, Mohan.Reddy AT analog.com)
    
      - Improved the regexp when collecting data from devices's
        interrupts which also fixes some annoying messages on
        using non-numeric arguments.
    
      - Added support for the Pure-FTPd logs in the 'serv' and
        'ftp' graphs.
    
        - Added the new configuration option 'https_url'. [#31]
    
        - Fixed error messages about use of uninitialized values
          in 'system' graph on BSD systems.
    
      - Fixed error messages about not numeric argument in
        addition in 'fs' graph on BSD systems.
    
      - Fixed in 'emailreports' to use the command line
        'hostname' if the variable $ENV{HOSTNAME} is not defined
        (Debian/Ubuntu and perhaps other systems). (thanks to
        Skibbi, skibbi AT gmail.com for pointing this out)
    
      - Fixed the error message 'String ends after the = sign on
        CDEF:allvalues=' in the 'int' graph (the Interrupts
        graph is pending to have a complete rewrite).
    
      - Fixed the 'int' graph in order to be more compatible
        with Raspberry Pi.
    
        - Fixed in 'bind.pm' to store a 0 value if threads are
          disabled. [#29]
    
        - Fixed to correctly sent images in graphs 'proc',
          'port' and 'fail2ban' when using emailreports. (thanks
          to Benoit Segond von Banchet, bjm.segondvonbanchet AT
          telfort.nl for pointing this out)
    
      - Fixed to show the real hostname in the emailreports.
    
        - Fixed the 'int' graph in order to be compatible with
          Excito B3 product. (thanks to Patrick Fallberg,
          patrick AT fallberg.net for pointing this out)
    
      - Fixed to correctly sanitize the input string in the
        built-in HTTP server which led into a number of security
        vulnerabilities. [#30]
    
      - Fixed the lack of minimum definition in some data
        sources of 'bind' graph. (thanks to Andreas Itzchak
        Rehberg, izzy AT qumran.org for pointing this out)
    
      - Fixed a fail to adequately sanitize request strings of
        malicious JavaScript. [#30] (thanks to Jacob Amey, jamey
        AT securityinspection.com for pointing this out)
    
      - Fixed a typo in monitorix.service. [#32]
    
        - Fixed the requests value in the 'nginx' graph. Now it
          honours the label to show the value per second,
          instead of per minute. (thanks to Martin Culak, culak
          AT firma.azet.sk for pointing this out)
    
      - Small fixes and typos.
