Description

This security bulletin contains information about 3 vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4442)

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

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


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

Monkey HTTP Daemon 0.9.3 retains the supplementary group IDs of the root account during operations with a non-root effective UID, which might allow local users to bypass intended file-read restrictions by leveraging a race condition in a file-permission check.


2) Link following (CVE-ID: CVE-2012-5303)

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


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

Monkey HTTP Daemon 0.9.3 might allow local users to overwrite arbitrary files via a symlink attack on a PID file, as demonstrated by a pathname different from the default /var/run/monkey.pid pathname.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4443)

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

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


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

Monkey HTTP Daemon 0.9.3 uses a real UID of root and a real GID of root during execution of CGI scripts, which might allow local users to gain privileges by leveraging cgi-bin write access.
