Description

This security bulletin contains information about 7 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2017-14083)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to improper validation of user supplied request. A remote attacker can send a specially crafted request and obtain the pre-authentication encryption key.

2) Remote code execution (CVE-ID: CVE-2017-14084)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to a flaw in the Send function in HttpTalk.php. A remote attacker can send a specially crafted request and execute arbitrary code with elevated privileges.

3) Information disclosure (CVE-ID: CVE-2017-14085)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to improper validation of user supplied request. A remote attacker can send a specially crafted request and obtain NT Domain and PHP information.

4) Remote code execution (CVE-ID: CVE-2017-14086)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote attacker to execute arbitrary code or cause DoS condition on the target system.

The weakness exists due to a flaw in fcgiOfcDDA.exe. A remote attacker can send a specially crafted request and cause denial of service or execute arbitrary code with elevated privileges.

5) Cross-site scripting (CVE-ID: CVE-2017-14087)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

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


The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in 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.


6) Privilege escalation (CVE-ID: CVE-2017-14088)

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

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


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to a flaw in the handling of IOCTL 0x220008 and 0x22006C within tmwfp.sys. A local attacker can escalate privileges to resources normally reserved for the kernel.

7) Memory corruption (CVE-ID: CVE-2017-14089)

CWE-ID: CWE-119 - Memory corruption

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


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to improper validation of user request in cgiShowClientAdm.exe. A remote attacker can send a specially crafted request, trigger memory corruption and cause the system to crash.

Successful exploitation of the vulnerability results in denial of service.
