Multiple vulnerabilities in IBM Flex System Chassis Management Module (CMM)

1) Denial of service

EUVDB-ID: #VU9333

Risk: Low

CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-15906

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote authenticated attacker to cause DoS condition on the target system.

The weakness exists in the process_open() function due to improper prevention of write operations in read-only mode. A remote attacker can create zero-length files and cause the service to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

Install update from vendor's website.

2) Null pointer dereference

EUVDB-ID: #VU14163

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-10708

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to improper processing of out-of-sequence NEWKEYS messages, as defined in the kex.c and packet.c source code files. A remote attacker can send an out-of-sequence NEWKEYS message, trigger a NULL pointer dereference condition and cause the sshd daemon to crash.

Mitigation

Install update from vendor's website.

3) Buffer overflow

EUVDB-ID: #VU2075

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-10012

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code on vulnerable system with root privileges.

The vulnerability exists in sshd due to a flaw in boundary checks in the shared memory manager that may be skipped by some optimizing compilers. A local user can trigger memory corruption and execute arbitrary code with root privileges. The issue is related to m_zback and m_zlib data structures.

Successful exploitation of this vulnerability may allow a local user to elevate privileges.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

4) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU103988

Risk: Medium

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2008-1483

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions. A local user can hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs.

Mitigation

Install update from vendor's website.
