Description

This security bulletin contains information about 3 vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2018-10728)

CWE-ID: CWE-121 - Stack-based buffer overflow

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:U/U:Amber


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

The weakness exists due to stack-based buffer overflow. A remote attacker can insert a specially crafted cookie into a GET request, trigger memory corruption and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

2) Information disclosure (CVE-ID: CVE-2018-10729)

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

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


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

The weakness exists due to Web interface CGI applications may copy the contents of the running configuration file to a commonly accessed file. A remote attacker can submit a web login request can expose the contents of this file through to the web browser.

3) Null pointer dereference (CVE-ID: CVE-2018-10754)

CWE-ID: CWE-476 - NULL Pointer Dereference

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


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

The vulnerability exists due to improper parsing of terminfo files by the _nc_write_entry function, as defined in the tinfo/parse_entry.c source code file. A remote attacker can trick the victim into open a terminfo file that submits malicious input, trigger a NULL pointer dereference condition and cause the application to crash.
