Multiple priviledge escalation vulnerabilities in Microsoft Windows

1) Privilege escalation

EUVDB-ID: #VU1341

Risk: Low

CVSSv4.0: 7.1 [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]

CVE-ID: CVE-2009-1126

CWE-ID: CWE-233 - Improper Handling of Parameters

Exploit availability: No

Description

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.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

2) Privilege escalation

EUVDB-ID: #VU1340

Risk: Low

CVSSv4.0: 5.9 [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]

CVE-ID: CVE-2009-1125

CWE-ID: CWE-622 - Improper Validation of Function Hook Argument

Exploit availability: No

Description

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

EUVDB-ID: #VU1339

Risk: Low

CVSSv4.0: 5.9 [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]

CVE-ID: CVE-2009-1124

CWE-ID: CWE-822 - Untrusted Pointer Dereference

Exploit availability: No

Description

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.
