A vulnerability in the 802.11 association frame validation of Cisco Catalyst 9100 Series Access Points (APs) 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 certain parameters within association request frames received by the AP. An attacker could exploit this vulnerability by sending a crafted 802.11 association request to a nearby device. An exploit could allow the attacker to unexpectedly reload the device, resulting in a DoS condition.

A vulnerability in the processing of Control and Provisioning of Wireless Access Points (CAPWAP) Mobility messages in Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family 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 and improper management of resources related to the handling of CAPWAP Mobility messages. An attacker could exploit this vulnerability by sending crafted CAPWAP Mobility packets to an affected device. A successful exploit could allow the attacker to exhaust resources on the affected device. This would cause the device to reload, resulting in a DoS condition.

A vulnerability in the processing of malformed Common Industrial Protocol (CIP) packets that are sent to Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to unexpectedly reload, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation during processing of CIP packets. An attacker could exploit this vulnerability by sending a malformed CIP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition.

A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to overwrite and possibly corrupt files on an affected system. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary commands that are executed as the root user account. A successful exploit could allow the attacker to overwrite arbitrary system files, which could result in a denial of service (DoS) condition.

Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function.

Multiple cross-site scripting (XSS) vulnerabilities in Canon Medical Vitrea View 7.x before 7.7.6 allow remote attackers to inject arbitrary web script or HTML via (1) the input after the error subdirectory to the /vitrea-view/error/ subdirectory, or the (2) groupID, (3) offset, or (4) limit parameter to an Administrative Panel (Group and Users) page. There is a risk of an attacker retrieving patient information.

A social engineering campaign leveraging job-themed lures is weaponizing a years-old remote code execution flaw in Microsoft Office to deploy Cobalt Strike beacons on compromised hosts. "The payload discovered is a leaked version of a Cobalt Strike beacon," Cisco Talos researchers Chetan Raghuprasad and Vanja Svajcer said in a new analysis published Wednesday. "The beacon configuration contains

drivers/char/pcmcia/synclink_cs.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling ioctl, aka a race condition between mgslpc_ioctl and mgslpc_detach.

By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  I’ve spent the past few months with my colleague Ashlee Benge looking at personal health apps’ privacy policies. We found several instances of apps that carry sensitive information stating they would share certain information with third-party advertisers and even law enforcement agencies, if necessary.  One of the most popular period-tracking apps on the Google Play store, Period Calendar Period Tracker, has a privacy policy that states it will "share information with law enforcement agencies, public authorities, or other organizations if We’re [sic] required by law to do so or if such use is reasonably necessary. We will carefully review all such requests to ensure that they have a legitimate basis and are limited to data that law enforcement is authorized to access for specific investigative purposes only."  A report from the Washington Post also released last week found that this app, as well...
