A privilege escalation vulnerability exists in the Web Interface functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted HTTP request can lead to execute priviledged operation. An attacker can visit a webpage to trigger this vulnerability.
A stack overflow vulnerability exists in the WebCam Server Login functionality of GeoVision GV-VMS V20 20.0.2. A specially crafted HTTP request can lead to an arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger this vulnerability.
An insufficient encryption vulnerability exists in the Device Authentication functionality of GeoVision GV-IP Device Utility 9.0.5. Listening to broadcast packets can lead to credentials leak. An attacker can listen to broadcast messages to trigger this vulnerability.
When interacting with various Geovision devices on the network, the utility may send privileged commands; in order to do so, the username and password of the device need to be provided. In some instances the command is broadcasted over UDP and the username/password are encrypted using a cryptographic protocol that appears to be derivated from Blowfish. However the symmetric key used for the encryption is also included in the packet, and thus the security of the username/password only relies on the "obscurity" of the encryption scheme. An attacker on the same LAN can listen to the broadcast traffic once an admin user interacts with the device, and decrypt the credentials using their own implementation of the algorithm. With this password the attacker would have full control over the device configuration, allowing them to change its ip address or even reset it to factory default.
Multiple reflected cross-site scripting (xss) vulnerabilities exist in the Web Interface / ssi.cgi functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted malicious url can lead to an arbitrary javascript code execution. An attacker can provide a crafted URL to trigger this vulnerability. Reflected XXS via the error message for requesting non-existing page.

#### Stack-overflow via unconstrained sscanf
The call to `sscanf` at [1] to split the `Buffer` variable into the `username` and `password` variables doesn't limit the size of the extracted content to match the destination buffers' sizes. In this case, if either the username or password decoded from the authorization string exceeds `40` characters (the size the stack variables `username` and `password`) then a stack overflow will occur.
The data is controlled by an attacker, but sronger constraints (e.g. no null bytes) may make exploitation harder. A successful attack could lead to full code execution as SYSTEM on the machine running the service.
An os command injection vulnerability exists in the DdnsSetting.cgi functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted DDNS configuration can lead to arbitrary command execution. An attacker can modify a configuration value to trigger this vulnerability.
A guessable session cookie vulnerability exists in the Web Interface functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted series of HTTP requests can lead to an authentication bypas. An attacker can bruteforce session cookies to trigger this vulnerability.

GeoVision GV-ASManager Missing Authorization Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of GeoVision GV-ASManager. Although authentication is required to exploit this vulnerability, default guest credentials may be used.
The specific flaw exists within the GV-ASWeb service. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-25394.
