Broadcom Fabric Operating System (FOS)

An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.

Multiple buffer overflow vulnerabilities in REST API in Brocade Fabric OS versions v8.2.1 through v8.2.1d, and 8.2.2 versions before v8.2.2c could allow remote unauthenticated attackers to perform various attacks.

A vulnerability in Brocade Fabric OS software v9.1.1, v9.0.1e, v8.2.3c, v7.4.2j, and earlier versions could allow a remote unauthenticated attacker to execute on a Brocade Fabric OS switch commands capable of modifying zoning, disabling the switch, disabling ports, and modifying the switch IP address.

Brocade Fabric OS before Brocade Fabric OS v8.2.1c, v8.1.2h, and all versions of Brocade Fabric OS v8.0.x and v7.x contain documented hard-coded credentials, which could allow attackers to gain access to the system.

Brocade Fabric OS versions before Brocade Fabric OS v9.0.0, v8.2.2c, v8.2.1e, v8.1.2k, v8.2.0_CBN3, contains code injection and privilege escalation vulnerability.

Rest API in Brocade Fabric OS v8.2.1 through v8.2.1d, and 8.2.2 versions before v8.2.2c is vulnerable to multiple instances of reflected input.

Remote code execution (RCE) vulnerability in Brocade Fabric OS after v9.0 and before v9.2.0 could allow an attacker to execute arbitrary code and use this to gain root access to the Brocade switch.

A vulnerability in the proxy service of Brocade Fabric OS versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow remote unauthenticated attackers to obtain sensitive information and possibly cause a denial of service attack.

RADIUS Protocol under RFC2865 is vulnerable to forgery attacks.

A privilege escalation vulnerability in Brocade Fibre Channel SAN products running Brocade Fabric OS (FOS) releases earlier than v7.4.1d and v8.0.1b could allow an authenticated attacker to elevate the privileges of user accounts accessing the system via command line interface. With affected versions, non-root users can gain root access with a combination of shell commands and parameters.

A vulnerability in the Brocade Webtools firmware update section of Brocade Fabric OS before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow remote authenticated attackers to execute arbitrary commands.

A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, 7.4.2.j could allow a remote authenticated attacker to perform stack buffer overflow using in “firmwaredownload” and “diagshow” commands.

Supportlink CLI in Brocade Fabric OS Versions v8.2.1 through v8.2.1d, and 8.2.2 versions before v8.2.2c does not obfuscate the password field, which could expose users’ credentials of the remote server. An authenticated user could obtain the exposed password credentials to gain access to the remote host.

Brocade Webtools in Brocade Fabric OS versions before Brocade Fabric OS versions v9.1.1, v9.0.1e, and v8.2.3c could allow a low privilege webtools, user, to gain elevated admin rights, or privileges, beyond what is intended or entitled for that user. By exploiting this vulnerability, a user whose role is not an admin can create a new user with an admin role using the operator session id. The issue was replicated after intercepting the admin, and operator authorization headers sent unencrypted and editing a user addition request to use the operator's authorization header.

A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, and 7.4.2j could allow a local authenticated user to break out of restricted shells with “set context” and escalate privileges.

License forgery in Brocade Fabric OS (FOS) hardware platforms running any version of Brocade Fabric OS software,

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.

HPE FOS before 7.4.1d and 8.x before 8.0.1 on StoreFabric B switches allows remote attackers to obtain sensitive information via unspecified vectors.

The command ipfilter in Brocade Fabric OS before Brocade Fabric OS v.9.0.1a, v8.2.3, and v8.2.0_CBN4, and v7.4.2h uses unsafe string function to process user input.
