Summary
A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel.
Severity
No CVSS data available.

Title
Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows Shared Memory Information Disclosure Vulnerability
Summary
A vulnerability in Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows could allow an authenticated, local attacker to gain access to sensitive information on an affected system. This vulnerability is due to the unsafe usage of shared memory by the affected software. An attacker with permissions to view system memory could exploit this vulnerability by running an application on the local system that is designed to read shared memory. A successful exploit could allow the attacker to retrieve sensitive information from the shared memory, including usernames, meeting information, or authentication tokens. Note: To exploit this vulnerability, an attacker must have valid credentials on a Microsoft Windows end-user system and must log in after another user has already authenticated with Webex on the same end-user system.

Vulnerability from github – Published: 2023-08-04 00:30 – Updated: 2024-01-25 18:30
VLAI
Details
A vulnerability in the scanning engines of Cisco AsyncOS Software for Cisco Secure Web Appliance could allow an unauthenticated, remote attacker to bypass a configured rule, allowing traffic onto a network that should have been blocked.
This vulnerability is due to improper detection of malicious traffic when the traffic is encoded with a specific content format. An attacker could exploit this vulnerability by using an affected device to connect to a malicious server and receiving crafted HTTP responses. A successful exploit could allow the attacker to bypass an explicit block rule and receive traffic that should have been rejected by the device.

Summary
AIOHTTP vulnerable to brute-force leak of internal static file path components
Details
Summary
Path normalization for static files prevents path traversal, but opens up the ability for an attacker to ascertain the existence of absolute path components.
Impact
If an application uses web.static() (not recommended for production deployments), it may be possible for an attacker to ascertain the existence of path components.

Details
A vulnerability in the API endpoints for Cisco DNA Center could allow an authenticated, remote attacker to gain access to sensitive information that should be restricted. The attacker must have valid device credentials. This vulnerability is due to improper access controls on API endpoints. An attacker could exploit the vulnerability by sending a specific API request to an affected application. A successful exploit could allow the attacker to obtain sensitive information about other users who are configured with higher privileges on the application.
