A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Fortinet FortiAuthenticator 3.0.0 allows local users to bypass intended restrictions and gain privileges by creating /tmp/privexec/dbgcore_enable_shell_access and executing the "shell" command.


3) Information disclosure (CVE-ID: CVE-2015-1457)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Fortinet FortiAuthenticator 3.0.0 allows local users to read arbitrary files via the -f flag to the dig command.


4) Information disclosure (CVE-ID: CVE-2015-1456)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote #AU# to gain access to sensitive information.

Fortinet FortiAuthenticator 3.0.0 logs the PostgreSQL usernames and passwords in cleartext, which allows remote administrators to obtain sensitive information by reading the log at debug/startup/.


5) Credentials management (CVE-ID: CVE-2015-1455)

CWE-ID: CWE-255 - Credentials Management

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Fortinet FortiAuthenticator 3.0.0 has a password of (1) slony for the slony PostgreSQL user and (2) www-data for the www-data PostgreSQL user, which makes it easier for remote attackers to obtain access via unspecified vectors.
