A vulnerability in the Simple Network Management Protocol (SNMP) of Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family could allow an authenticated, remote attacker to access sensitive information. This vulnerability is due to insufficient restrictions that allow a sensitive configuration detail to be disclosed. An attacker could exploit this vulnerability by retrieving data through SNMP read-only community access. A successful exploit could allow the attacker to view Service Set Identifier (SSID) preshared keys (PSKs) that are configured on the affected device.

A vulnerability in the smart card login authentication of Cisco Duo for macOS could allow an unauthenticated attacker with physical access to bypass authentication. This vulnerability exists because the assigned user of a smart card is not properly matched with the authenticating user. An attacker could exploit this vulnerability by configuring a smart card login to bypass Duo authentication. A successful exploit could allow the attacker to use any personal identity verification (PIV) smart card for authentication, even if the smart card is not assigned to the authenticating user.

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.

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...

A memory corruption vulnerability exists in the libpthread linuxthreads functionality of uClibC 0.9.33.2 and uClibC-ng 1.0.40. Thread allocation can lead to memory corruption. An attacker can create threads to trigger this vulnerability.
