Information disclosure in Brocade Fabric OS before 9.2.1c2, 9.2.2 through 9.2.2a and 10.0.0

An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).

Brocade Fabric OS versions prior to v9.0 have default community strings

An OS command injection vulnerability exists in the PAM (Pluggable Authentication Module) session cleanup routines during SSH session termination on Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user authenticating via an external directory or AAA service whose username or profile identifier contains shell metacharacters can trigger arbitrary command execution with root privileges when their remote SSH session closes.

An authentication logic and privilege escalation vulnerability exists in the account management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. Under specific conditions, an authenticated user can bypass authorization restrictions intended to prevent modifying another account's access privileges. Exploitation allows a lower-privileged user to assign administrative roles to a target account, leading to localized privilege escalation.

scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."

A memory leak in the crypto_reportstat() function in crypto/crypto_user_stat.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_reportstat_alg() failures, aka CID-c03b04dcdba1.

A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dma_get_sgtable() failures, aka CID-fc739a058d99.

A Vulnerability in the supportsave command of Brocade Fabric OS command line interface (CLI) versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow a local attacker to escape the restricted shell and, gain root access.

A Vulnerability in the configdownload command of Brocade Fabric OS command line interface (CLI) versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow a local attacker to escape the restricted shell and, gain root access.

Privilege escalation via the fosexec command

The request handling functions in web management interface of Brocade Fabric OS versions before v9.0.1a, v8.2.3a, and v7.4.2h do not properly handle malformed user input, resulting in a service crash. An authenticated attacker could use this weakness to cause the FOS HTTP application handler to crash, requiring a reboot.

A vulnerability in the authentication mechanism of Brocade Fabric OS versions before Brocade Fabric OS v.9.0.1a, v8.2.3a and v7.4.2h could allow a user to Login with empty password, and invalid password through telnet, ssh and REST.

Knowledge of full path name

A privilege escalation vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, could allow a local authenticated user to escalate its privilege to root using switch commands “supportlink”, “firmwaredownload”, “portcfgupload, license, and “fosexec”.

A memory buffer overflow vulnerability exists in the internal diagnostic and route validation routines used by the Fabric Shortest Path First (FSPF) protocol component of Brocade Fabric OS versions before 10.0.1. While this code path is part of internal diagnostic functionality and is not directly accessible via standard user interfaces or CLI management commands, an input processing flaw allows incoming or internally routed diagnostic state payloads to exceed allocated memory boundaries. An attacker that is able to chain or link other vulnerabilities to exploit this internal diagnostic could cause a heap- or stack-based memory overrun, resulting in a daemon crash (Denial of Service) or potential arbitrary code execution within the context of the routing daemon.

A privilege escalation vulnerability exists in the internal Command-Line Interface (CLI) authorization handling mechanism of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user or local process that can manipulate the process execution environment can bypass Role-Based Access Control (RBAC) validation checks. Successful exploitation allows an attacker to elevate privileges to root

Segmentation fault in SSL_check_chain

An information disclosure vulnerability exists in curl 7.65.0 to 7.82.0 are vulnerable that by using an IPv6 address that was in the connection pool but with a different zone id it could reuse a connection instead.

Brocade Fabric OS Versions before v7.4.2f, v8.2.2a, v8.1.2j and v8.2.1d could expose external passwords, common secrets or authentication keys used between the switch and an external server.

A vulnerability in the management interface in Brocade Fabric OS Versions before Brocade Fabric OS v9.0.0 could allow a remote attacker to perform a denial of service attack on the vulnerable host.

Brocade Fabric OS Versions before v8.2.2a and v8.2.1d could expose the credentials of the remote ESRS server when these credentials are given as a command line option when configuring the ESRS client.

A vulnerability in the web management interface of Brocade Fabric OS versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow attackers to intercept or manipulate a user's session ID.

Running security scans against the SAN switch can cause config and secnotify processes within the firmware before Brocade Fabric OS v9.0.0, v8.2.2d and v8.2.1e to consume all memory leading to denial of service impacts possibly including a switch panic.

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)

SFTP/FTP password could be captured in plain text in Supportsave generated from SANnav

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.

Brocade Fabric OS may capture SNMP Passwords in clear text

The host SSH servers of Brocade Fabric OS before Brocade Fabric OS v7.4.2h, v8.2.1c, v8.2.2, v9.0.0, and Brocade SANnav before v2.1.1 utilize keys of less than 2048 bits, which may be vulnerable to man-in-the-middle attacks and/or insecure SSH communications.
