Cisco NX-OS CLI Command Software Image Signature Verification Vulnerabilities

A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device.

An attacker could exploit this vulnerability to install an unsigned software image on an affected device.

Cisco Nexus 3000 Series and 9000 Series Switches in NX-OS Mode CLI Command Software Image Signature Verification Vulnerability

A vulnerability in the Image Signature Verification feature used in an NX-OS CLI command in Cisco Nexus 3000 Series and 9000 Series Switches could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device. Note: If the device has not been patched for the vulnerability previously disclosed in the Cisco Security Advisory cisco-sa-20190306-nxos-sig-verif, a successful exploit could allow the attacker to boot a malicious software image.

Cisco NX-OS Software Patch Signature Verification Bypass Vulnerability

A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image.

Cisco MDS 9700 Series Multilayer Directors and Nexus 7000/7700 Series Switches Software Patch Signature Verification Vulnerability

A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by loading an unsigned software patch on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image.

Multiple Cisco UCS-Based Products UEFI Secure Boot Bypass Vulnerability

A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical attacker to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker to bypass the signature validation checks that are done by UEFI Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.

Cisco NX-OS Software Arbitrary File Overwrite Vulnerability

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. The attacker must have valid administrator credentials for the affected device to exploit this vulnerability.

Cisco FXOS and NX-OS Software Secure Configuration Bypass Vulnerability

A vulnerability in the Secure Configuration Validation functionality of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to run arbitrary commands at system boot time with the privileges of root. The vulnerability is due to a lack of proper validation of system files when the persistent configuration information is read from the file system. An attacker could exploit this vulnerability by authenticating to the device and overwriting the persistent configuration storage with malicious executable files. An exploit could allow the attacker to run arbitrary commands at system startup and those commands will run as the root user. The attacker must have valid administrative credentials for the device.

Cisco NX-OS Software Image Signature Verification Vulnerability

A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability is due to improper verification of digital signatures for software images. An attacker could exploit this vulnerability by loading an unsigned software image on an affected device. A successful exploit could allow the attacker to boot a malicious software image. Note: The fix for this vulnerability requires a BIOS upgrade as part of the software upgrade. For additional information, see the Details section of this advisory. Nexus 3000 Series Switches are affected running software versions prior to 7.0(3)I7(5). Nexus 9000 Series Fabric Switches in ACI Mode are affected running software versions prior to 13.2(1l). Nexus 9000 Series Switches in Standalone NX-OS Mode are affected running software versions prior to 7.0(3)I7(5). Nexus 9500 R-Series Line Cards and Fabric Modules are affected running software versions prior to 7.0(3)F3(5).

wolfSSL before 4.3.0 mishandles calls to wc_SignatureGenerateHash, leading to fault injection in RSA cryptography.

Norton Password Manager, prior to 6.6.2.5, may be susceptible to a cross origin resource sharing (CORS) vulnerability, which is a type of issue that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served.

Reportexpress ProPlus contains a vulnerability that could allow an arbitrary code execution by inserted VBscript into the configure file(rxp).

An issue was discovered in TitanHQ WebTitan before 5.18. It contains a Remote Code Execution issue through which an attacker can execute arbitrary code as root. The issue stems from the hotfix download mechanism, which downloads a shell script via HTTP, and then executes it as root. This is analogous to CVE-2019-6800 but for a different product.

Deprecated functionality in autoyast2 automatically imports gpg keys without checking them
