CVE-2019-17093 (GCVE-0-2019-17093)

Vulnerability from nvd – Published: 2019-10-23 16:59 – Updated: 2024-08-05 01:33

Summary

An issue was discovered in Avast antivirus before 19.8 and AVG antivirus before 19.8. A DLL Preloading vulnerability allows an attacker to implant %WINDIR%\system32\wbemcomn.dll, which is loaded into a protected-light process (PPL) and might bypass some of the self-defense mechanisms. This affects all components that use WMI, e.g., AVGSvc.exe 19.6.4546.0 and TuneupSmartScan.dll 19.1.884.0.

CVE-2017-5566 (GCVE-0-2017-5566)

Vulnerability from nvd – Published: 2017-03-21 16:00 – Updated: 2024-08-05 15:04

Summary

Code injection vulnerability in AVG Ultimate 17.1 (and earlier), AVG Internet Security 17.1 (and earlier), and AVG AntiVirus FREE 17.1 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any AVG process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack.

Severity

No CVSS data available.

CVE-2010-3498 (GCVE-0-2010-3498)

Vulnerability from nvd – Published: 2012-08-22 10:00 – Updated: 2024-09-17 02:46

Summary

AVG Anti-Virus does not properly interact with the processing of hcp:// URLs by the Microsoft Help and Support Center, which makes it easier for remote attackers to execute arbitrary code via malware that is correctly detected by this product, but with a detection approach that occurs too late to stop the code execution.

Severity

No CVSS data available.

Vulnerability from cvelistv5 – Published: 2024-11-22 21:12 – Updated: 2024-12-05 14:29

Title

AVG AntiVirus Free AVGSvc Link Following Local Privilege Escalation Vulnerability

Summary

AVG AntiVirus Free AVGSvc Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of AVG AntiVirus Free. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the AVG Service. By creating a symbolic link, an attacker can abuse the service to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-22260.

Severity

CVE-2019-17093 (GCVE-0-2019-17093)

Vulnerability from cvelistv5 – Published: 2019-10-23 16:59 – Updated: 2024-08-05 01:33

Summary

An issue was discovered in Avast antivirus before 19.8 and AVG antivirus before 19.8. A DLL Preloading vulnerability allows an attacker to implant %WINDIR%\system32\wbemcomn.dll, which is loaded into a protected-light process (PPL) and might bypass some of the self-defense mechanisms. This affects all components that use WMI, e.g., AVGSvc.exe 19.6.4546.0 and TuneupSmartScan.dll 19.1.884.0.

CVE-2017-5566 (GCVE-0-2017-5566)

Vulnerability from cvelistv5 – Published: 2017-03-21 16:00 – Updated: 2024-08-05 15:04

Summary

Code injection vulnerability in AVG Ultimate 17.1 (and earlier), AVG Internet Security 17.1 (and earlier), and AVG AntiVirus FREE 17.1 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any AVG process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack.

CVE-2010-3498 (GCVE-0-2010-3498)

Vulnerability from cvelistv5 – Published: 2012-08-22 10:00 – Updated: 2024-09-17 02:46

Summary

AVG Anti-Virus does not properly interact with the processing of hcp:// URLs by the Microsoft Help and Support Center, which makes it easier for remote attackers to execute arbitrary code via malware that is correctly detected by this product, but with a detection approach that occurs too late to stop the code execution.

Severity

No CVSS data available.
