Description
This security bulletin contains information about 4 vulnerabilities.
1) Privilege escalation (CVE-ID: CVE-2009-1126)
CWE-ID: CWE-233 - Improper Handling of Parameters
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:P/U:Clear
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to improper validation of user-mode input. By running a malicious application, a local attacker can edit an unspecified desktop parameter and execute arbitrary code in kernel mode.
Successful exploitation of the vulnerability results in privilege escalation allowing to execute arbitrary code and take complete control of an affected system.
2) Privilege escalation (CVE-ID: CVE-2009-1125)
CWE-ID: CWE-622 - Improper Validation of Function Hook Argument
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 improper validation of an argument to an unspecified system call. By running a malicious application, a local attacker can submit malformed calls to the Windows Kernel and execute arbitrary code in kernel mode.
Successful exploitation of the vulnerability results in privilege escalation allowing to execute arbitrary code and take complete control of an affected system.
3) Privilege escalation (CVE-ID: CVE-2009-1124)
CWE-ID: CWE-822 - Untrusted Pointer Dereference
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 improper validation of changes in certain kernel objects. By running a malicious application, a local attacker can submit malformed calls to the Windows Kernel and execute arbitrary code in kernel mode.
Successful exploitation of the vulnerability results in privilege escalation allowing to execute arbitrary code and take complete control of an affected system.
4) Privilege escalation (CVE-ID: CVE-2009-1123)
CWE-ID: CWE-822 - Untrusted Pointer Dereference
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:A/U:Green
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to improper validation of changes in certain kernel objects. By running a malicious application, a local attacker can submit malformed calls to the Windows Kernel and execute arbitrary code in kernel mode.
Successful exploitation of the vulnerability results in privilege escalation allowing to execute arbitrary code and take complete control of an affected system.
Note: according to reports this vulnerability was being actively exploited before Microsoft issued security patch.
