Vulnerabilidades de Brocade

An out-of-bounds memory read vulnerability exists in the web management daemon of Brocade Fabric OS versions before 10.0.1. Unauthenticated HTTP endpoints process specific URL query parameters without validating array index boundaries or performing numerical range checks. An unauthenticated remote attacker can exploit this issue by sending a single, crafted HTTP request containing extreme numerical values in the query string. This causes an invalid memory dereference, resulting in a crash of the web management process (Denial of Service) and potential temporary management-plane disruption.

A stack-based buffer overflow vulnerability exists in the Internet Key Exchange (IKEv2) protocol handler on Brocade Fabric OS versions before 10.0.1. The vulnerability occurs when processing initial IKE key exchange requests on extension switches or blades running IPsec-enabled Fibre Channel over IP (FCIP) circuits. An unauthenticated remote attacker can exploit this vulnerability by sending a single, specifically crafted UDP packet (Port 500) containing an oversized Nonce payload. Successful exploitation results in a denial of service (data-plane process crash)

Multiple stack-based buffer overflow vulnerabilities exist in the REST API management component of Brocade Fabric OS versions prior to 10.0.1. When processing API request payloads (such as device configuration attributes or port mapping requests) the REST API service fails to properly validate incoming array counts and string lengths against internal buffer capacities. An authenticated attacker with REST API access can transmit crafted, oversized request parameters to induce memory corruption on the execution stack. This may result in a denial-of-service condition (daemon crash) or potential arbitrary code execution within the management process context.

Multiple OS Command Injection vulnerabilities exist in the management interface and session processing routines of Brocade Fabric OS versions before 10.0.1. Input processing flaws during remote management connection validation and session verification for directory-based user accounts allow untrusted input containing shell metacharacters to reach internal system execution wrappers. An authenticated user or a compromised directory service account can exploit these vulnerabilities to execute arbitrary operating system commands with elevated privileges on the target device.

A command injection vulnerability in the REST API management interface of Brocade Fabric OS versions before 10.0.1 allows an authenticated user to execute arbitrary system commands via crafted input parameters.

When Brocade Fabric OS versions before 10.0.1 processes trunk configuration operations, the application parses user-supplied list strings into dynamically allocated heap arrays without enforcing boundary checks on the maximum allowable number of elements. An authenticated administrator can exploit this vulnerability via crafted REST API requests containing an excessive number of list delimiters, causing heap corruption that can result in service crash or arbitrary code execution.

Incomplete log sanitization during bulk IPsec policy collection in Brocade SANnav versions before 3.0.1a permit extension switch pre-shared keys to be written to system logs. Individuals with read access to container logs or support archives can obtain these keys, leading to the potential compromise of encrypted network tunnels.

Improper handling of sensitive data during IPsec policy creation and modification in Brocade SANnav versions before 3.0.1a results in pre-shared keys being recorded in application logs. Individuals with read access to system log files or support bundles can view these credentials, leading to the potential exposure of keys used to secure network tunnels.

Plaintext exposure of sensitive authentication data in Brocade SANnav discovery service log files enables individuals with file read access to retrieve administrative switch credentials and active session tokens. An attacker with access to system logs or support bundles can leverage exposed authentication details to compromise managed network infrastructure and access active application sessions. This vulnerability affects Brocade SANnav versions before 3.0.1a.

Unauthenticated remote command injection in the Brocade SANnav orchestrator HTTP service permits network-adjacent attackers to execute arbitrary administrative switch CLI commands and issue container management instructions. This could allow an attacker to alter Fibre Channel fabric switch configurations or manipulate application container runtimes. This vulnerability affects Brocade SANnav versions before 3.0.1a.

Insufficient input sanitization of shell metacharacters in the Brocade SANnav CLI scripting component permits authenticated users to break out of restricted execution contexts on managed switches. An attacker with command execution permissions can leverage this flaw to run unauthorized shell commands across target fabric switches, bypassing command allow-lists and obtaining full administrative switch access. This vulnerability affects all Brocade SANnav versions before 3.0.1a.

Insecure access controls on internal service ports in Brocade SANnav versions before 3.0.1a allow local, non-administrative host users to communicate directly with backend management services. A local attacker can leverage this exposed access to transmit commands to connected Fabric OS switches under the security context of the SANnav management user.

Authentication bypass in Brocade ASCG 3.4.0 Could allow an unauthorized user to perform ASCG operations related to Brocade Support Link(BSL) and streaming configuration. and could even disable the ASCG application or disable use of BSL data collection on Brocade switches within the fabric.

A vulnerability in Brocade Fabric OS before 9.2.1c3 could allow elevating the privileges of the local authenticated user to “root” using the export option of seccertmgmt and seccryptocfg commands.

A vulnerability in Brocade Fabric OS could allow an authenticated, local attacker with privileges to access the Bash shell to access insecurely stored file contents including the history command.
