CVSS: 6.7EPSS: 0%CPEs: 22EXPL: 0CVE-2019-1729 – Cisco NX-OS Software Arbitrary File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2019-1729
A vulnerability in the CLI implementation of a specific command used for image maintenance for Cisco NX-OS Software could allow an authenticated, local attacker to overwrite any file on the file system including system files. These file overwrites by the attacker are accomplished at the root privilege level. The vulnerability occurs because there is no verification of user-input parameters and or digital-signature verification for image files when using a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device and issuing a command at the CLI. Because an exploit could allow the attacker to overwrite any file on the disk, including system files, a denial of service (DoS) condition could occur. • http://www.securityfocus.com/bid/108378 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-file-write • CWE-20: Improper Input Validation CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.2EPSS: 0%CPEs: 211EXPL: 0CVE-2019-1649 – Cisco Secure Boot Hardware Tampering Vulnerability
https://notcve.org/view.php?id=CVE-2019-1649
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. • http://www.securityfocus.com/bid/108350 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot https://www.kb.cert.org/vuls/id/400865 https://www.us-cert.gov/ics/advisories/icsa-20-072-03 • CWE-284: Improper Access Control CWE-667: Improper Locking •
CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2019-1604 – Cisco NX-OS Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1604
A vulnerability in the user account management interface of Cisco NX-OS Software could allow an authenticated, local attacker to gain elevated privileges on an affected device. The vulnerability is due to an incorrect authorization check of user accounts and their associated Group ID (GID). An attacker could exploit this vulnerability by taking advantage of a logic error that will permit the use of higher privileged commands than what is necessarily assigned. A successful exploit could allow an attacker to execute commands with elevated privileges on the underlying Linux shell of an affected device. Nexus 7000 and 7700 Series Switches are affected in versions prior to 6.2(22), 8.2(3), and 8.3(2). • http://www.securityfocus.com/bid/107323 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-privesca • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2019-1603 – Cisco NX-OS Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1603
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to escalate lower-level privileges to the administrator level. The vulnerability is due to insufficient authorization enforcement. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. A successful exploit could allow an attacker to make configuration changes to the system as administrator. Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(4). • http://www.securityfocus.com/bid/107328 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-privesc • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
CVSS: 8.6EPSS: 0%CPEs: 29EXPL: 0CVE-2019-1597 – Cisco FXOS and NX-OS Lightweight Directory Access Protocol Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1597
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 •
