A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected.

### Impact All versions of Argo CD starting with v0.5.0 are vulnerable to an information disclosure bug allowing unauthorized users to enumerate application names by inspecting API error messages. An attacker could use the discovered application names as the starting point of another attack. For example, the attacker might use their knowledge of an application name to convince an administrator to grant higher privileges (social engineering). Many Argo CD API endpoints accept an application name as the only parameter. Since Argo CD RBAC requires both the application name and its configured project name (and, if apps-in-any-namespace is enabled, the application's namespace), Argo CD fetches the requested application before performing the RBAC check. If the application does not exist, the API returns a "not found". If the application does exist, and the user does not have access, the API returns an "unauthorized" error. By trial and error, an attacker can infer which applications exist ...

### Summary CWE-532: Insertion of Sensitive Information into Log File discovered in v9.23.1. The `directus_refresh_token` is not redacted properly from the log outputs and can be used to impersonate users without their permission. ### Details Using `v9.23.1`, I am seeing that the `directus_refresh_token` is not properly redacted as indicated by https://github.com/directus/directus/blob/7c479c5161639aac466c763b6b958a9524201d74/api/src/logger.ts#L13 I'm classifying this as a security vulnerability because if someone has access to the log outputs, for example with a shared Cloud account or Splunk implementation, they could exchange the refresh token using `/auth/refresh` for an access token and use the token to perform actions on behalf of an unsuspecting user. This situation creates issues with accountability and non-repudiation because we can no longer have confidence that actions taken in the application were authorized or even performed by the logged-in user. A couple of exampl...

A vulnerability in the Cisco IOx application hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. This vulnerability is due to insufficient restrictions on the hosted application. An attacker could exploit this vulnerability by logging in to and then escaping the Cisco IOx application container. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges.

A vulnerability in the implementation of the IPv4 Virtual Fragmentation Reassembly (VFR) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper reassembly of large packets that occurs when VFR is enabled on either a tunnel interface or on a physical interface that is configured with a maximum transmission unit (MTU) greater than 4,615 bytes. An attacker could exploit this vulnerability by sending fragmented packets through a VFR-enabled interface on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

A vulnerability in Cisco access points (AP) software could allow an authenticated, local attacker to inject arbitrary commands and execute them with root privileges. This vulnerability is due to improper input validation of commands that are issued from a wireless controller to an AP. An attacker with Administrator access to the CLI of the controller could exploit this vulnerability by issuing a command with crafted arguments. A successful exploit could allow the attacker to gain full root access on the AP.

A vulnerability in the HTTP-based client profiling feature of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of received traffic. An attacker could exploit this vulnerability by sending crafted traffic through a wireless access point. A successful exploit could allow the attacker to cause CPU utilization to increase, which could result in a DoS condition on an affected device and could cause new wireless client associations to fail. Once the offending traffic stops, the affected system will return to an operational state and new client associations will succeed.

A vulnerability in the access point (AP) joining process of the Control and Provisioning of Wireless Access Points (CAPWAP) protocol of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to a logic error that occurs when certain conditions are met during the AP joining process. An attacker could exploit this vulnerability by adding an AP that is under their control to the network. The attacker then must ensure that the AP successfully joins an affected wireless controller under certain conditions. Additionally, the attacker would need the ability to restart a valid AP that was previously connected to the controller. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition.

A vulnerability in the Meraki onboarding feature of Cisco IOS XE Software could allow an authenticated, local attacker to gain root level privileges on an affected device. This vulnerability is due to insufficient memory protection in the Meraki onboarding feature of an affected device. An attacker could exploit this vulnerability by modifying the Meraki registration parameters. A successful exploit could allow the attacker to elevate privileges to root.

A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands with elevated privileges. This vulnerability is due to insufficient input validation by the system CLI. An attacker with privileges to run commands could exploit this vulnerability by first authenticating to an affected device using either local terminal access or a management shell interface and then submitting crafted input to the system CLI. A successful exploit could allow the attacker to execute commands on the underlying operating system with root-level privileges. An attacker with limited user privileges could use this vulnerability to gain complete control over the system.
