Realtek Audio Service 1.0.0.55 Unquoted Service Path Privilege Escalation
Realtek Audio Service 1.0.0.55 contains an unquoted service path vulnerability in RtkAudioService64.exe that allows local attackers to escalate privileges by injecting malicious code. Attackers can place executable files in the unquoted service path directory to execute arbitrary code with LocalSystem privileges during service startup or system reboot.

Realtek Andrea RT Filters 1.0.64.7 - 'AERTSr64.EXE' Unquoted Service Path
Realtek Andrea RT Filters 1.0.64.7 contains an unquoted service path vulnerability that allows local users to potentially execute arbitrary code with elevated system privileges. Attackers can exploit the unquoted path in 'C:\Program Files\IDT\WDM\AESTSr64.exe' to inject malicious code that would execute during service startup or system reboot.

Realtek AP-Router SDK Buffer Overflow Vulnerability
Realtek Jungle SDK version v2.x up to v3.4.14B provides an HTTP web server exposing a management interface that can be used to configure the access point. Two versions of this management interface exists: one based on Go-Ahead named webs and another based on Boa named boa. Both of them are affected by these vulnerabilities. Specifically, these binaries are vulnerable to the following issues: - stack buffer overflow in formRebootCheck due to unsafe copy of submit-url parameter - stack buffer overflow in formWsc due to unsafe copy of submit-url parameter - stack buffer overflow in formWlanMultipleAP due to unsafe copy of submit-url parameter - stack buffer overflow in formWlSiteSurvey due to unsafe copy of ifname parameter - stack buffer overflow in formStaticDHCP due to unsafe copy of hostname parameter - stack buffer overflow in formWsc due to unsafe copy of 'peerPin' parameter - arbitrary command execution in formSysCmd via the sysCmd parameter - arbitrary command injection in formWsc via the 'peerPin' parameter Exploitability of identified issues will differ based on what the end vendor/manufacturer did with the Realtek SDK webserver. Some vendors use it as-is, others add their own authentication implementation, some kept all the features from the server, some remove some of them, some inserted their own set of features. However, given that Realtek SDK implementation is full of insecure calls and that developers tends to re-use those examples in their custom code, any binary based on Realtek SDK webserver will probably contains its own set of issues on top of the Realtek ones (if kept). Successful exploitation of these issues allows remote attackers to gain arbitrary code execution on the device.

Realtek Jungle SDK Remote Code Execution Vulnerability
Realtek Jungle SDK version v2.x up to v3.4.14B provides a diagnostic tool called 'MP Daemon' that is usually compiled as 'UDPServer' binary. The binary is affected by multiple memory corruption vulnerabilities and an arbitrary command injection vulnerability that can be exploited by remote unauthenticated attackers.
