A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of arguments that are passed to specific CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying More info: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-cli-cmdinject-euQVK9u?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=Cisco%20NX-OS%20Software%20CLI%20Command%20Injection%20Vulnerability&vs_k=1

For certain products that are running Cisco NX-OS Software and are configured for SSH authentication with an X.509 version 3 (X.509v3) certificate, two remote authorization methods are unsupported and could allow for privilege escalation: TACACS+ and certain configurations of Lightweight Directory Access Protocol (LDAP). TACACS+ does not properly validate the distinguished name (DN) of the X.509v3 certificate due to a logic error with authentication, authorization, and accounting (AAA). LDAP More info: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-x509v3-unsupportedconfig-ScRtAbUk?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=Cisco%20NX-OS%20Software%20SSH%20X.509v3%20Certificate%20Authentication%20with%20Unsupported%20Remote%20Authorization%20Method%20Privilege%20Escalation%20Issues&vs_k=1

A vulnerability in the Link Layer Discovery Protocol (LLDP) feature for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) Mode could allow an unauthenticated, adjacent attacker to cause a memory leak, which could result in an unexpected reload of the device. This vulnerability is due to incorrect error checking when parsing ingress LLDP packets. An attacker could exploit this vulnerability by sending a steady stream of crafted LLDP packets to an affected More info: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aci-lldp-dos-ySCNZOpX?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=Cisco%20Nexus%209000%20Series%20Fabric%20Switches%20in%20ACI%20Mode%20Link%20Layer%20Discovery%20Protocol%20Memory%20Leak%20Denial%20of%20Service%20Vulnerability&vs_k=1

A vulnerability in the backup configuration feature of Cisco UCS Manager Software and in the configuration export feature of Cisco FXOS Software could allow an unauthenticated attacker with access to a backup file to decrypt sensitive information stored in the full state and configuration backup files. This vulnerability is due to a weakness in the encryption method used for the backup function. An attacker could exploit this vulnerability by leveraging a static key used for the backup More info: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucsm-bkpsky-H8FCQgsA?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=Cisco%20FXOS%20Software%20and%20UCS%20Manager%20Software%20Configuration%20Backup%20Static%20Key%20Vulnerability&vs_k=1

On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code. This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write. An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to More info: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-clamav-q8DThCy?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=ClamAV%20HFS+%20Partition%20Scanning%20Buffer%20Overflow%20Vulnerability%20Affecting%20Cisco%20Products:%20February%202023&vs_k=1

A vulnerability in the Cisco IOx application hosting environment could allow an authenticated, remote attacker to execute arbitrary commands as root on the underlying host operating system. This vulnerability is due to incomplete sanitization of parameters that are passed in for activation of an application. An attacker could exploit this vulnerability by deploying and activating an application in the Cisco IOx application hosting environment with a crafted activation payload file.

A vulnerability in the scanning engines of Cisco AsyncOS Software for Cisco Secure Web Appliance, formerly known as Cisco Web Security Appliance (WSA), could allow an unauthenticated, remote attacker to bypass a configured rule, thereby allowing traffic onto a network that should have been blocked. This vulnerability exists because malformed, encoded traffic is not properly detected. An attacker could exploit this vulnerability by connecting through an affected device to a malicious server and More info: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wsa-bypass-bwBfugek?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=Cisco%20Secure%20Web%20Appliance%20Content%20Encoding%20Filter%20Bypass%20Vulnerability&vs_k=1

Greetings from the VMware Security Response Center! We wanted to address the recently reported ESXiArgs ransomware attacks as well as provide some guidance on actions concerned customers should take to protect themselves. VMware has not found evidence that suggests an unknown vulnerability (0-day) is being used to propagate the ransomware used in these recent attacks. … ContinuedThe post VMware Security Response Center (vSRC) Response to ‘ESXiArgs’ Ransomware Attacks appeared More info: https://blogs.vmware.com/security/2023/02/83330.html?utm_source=rss&utm_medium=rss&utm_campaign=83330
