CVE-2019-1601 – Cisco NX-OS Software Unauthorized Filesystem Access Vulnerability
https://notcve.org/view.php?id=CVE-2019-1601
A vulnerability in the filesystem permissions of Cisco NX-OS Software could allow an authenticated, local attacker to gain read and write access to a critical configuration file. The vulnerability is due to a failure to impose strict filesystem permissions on the targeted device. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow an attacker to use the content of this configuration file to bypass authentication and log in as any user of the device. MDS 9000 Series Multilayer Switches are affected in versions prior to 6.2(25), 8.1(1b), and 8.3(1). • http://www.securityfocus.com/bid/107404 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-file-access • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2019-1600 – Cisco FXOS and NX-OS Software Unauthorized Directory Access Vulnerability
https://notcve.org/view.php?id=CVE-2019-1600
A vulnerability in the file system permissions of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to access sensitive information that is stored in the file system of an affected system. The vulnerability is due to improper implementation of file system permissions. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow the attacker to access sensitive and critical files. Firepower 4100 Series Next-Generation Firewalls are affected in versions prior to 2.2.2.91 and 2.3.1.110. • http://www.securityfocus.com/bid/107399 http://www.securityfocus.com/bid/107404 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-directory • CWE-264: Permissions, Privileges, and Access Controls CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2019-1599 – Cisco NX-OS Software Netstack Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1599
A vulnerability in the network stack of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to an issue with allocating and freeing memory buffers in the network stack. An attacker could exploit this vulnerability by sending crafted TCP streams to an affected device in a sustained way. A successful exploit could cause the network stack of an affected device to run out of available buffers, impairing operations of control plane and management plane protocols, resulting in a DoS condition. Note: This vulnerability can be triggered only by traffic that is destined to an affected device and cannot be exploited using traffic that transits an affected device. • http://www.securityfocus.com/bid/107342 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-netstack • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-1598 – Cisco FXOS and NX-OS Lightweight Directory Access Protocol Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1598
Multiple vulnerabilities in the implementation of the Lightweight Directory Access Protocol (LDAP) feature in Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to the improper parsing of LDAP packets by an affected device. An attacker could exploit these vulnerabilities by sending an LDAP packet crafted using Basic Encoding Rules (BER) to an affected device. The LDAP packet must have a source IP address of an LDAP server configured on the targeted device. A successful exploit could cause the affected device to reload, resulting in a DoS condition. • http://www.securityfocus.com/bid/107394 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxosldap • CWE-20: Improper Input Validation •
CVE-2019-1596 – Cisco NX-OS Software Bash Shell Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1596
A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level to root. The attacker must authenticate with valid user credentials. The vulnerability is due to incorrect permissions of a system executable. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Bash prompt. A successful exploit could allow the attacker to escalate their privilege level to root. • http://www.securityfocus.com/bid/107340 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-pe • CWE-264: Permissions, Privileges, and Access Controls CWE-732: Incorrect Permission Assignment for Critical Resource •
