vulnerability note CVE-2012-0338 CVE-2012-0339

Cisco IOS: SSH/Telnet connection via VRF

Synthesis of the vulnerability

An attacker can connect with SSH/Telnet on Cisco IOS from a VRF (Virtual Routing and Forwarding) interface, even if "vrf-also" is not used.
Impacted products: IOS by Cisco, Cisco Router.
Severity: 2/4.
Consequences: user access/rights.
Provenance: intranet client.
Number of vulnerabilities in this bulletin: 2.
Creation date: 04/05/2012.
Identifiers: CSCsi77774, CSCsv86113, CVE-2012-0338, CVE-2012-0339, VIGILANCE-VUL-11584.

Description of the vulnerability

The "access-class" command defines access classes associated to an ACL.

The "vrf-also" argument is used to accept incoming connections from an interface belonging to a VRF (Virtual Routing and Forwarding). However, this argument is always set.

An attacker can therefore connect with SSH/Telnet on Cisco IOS from a VRF (Virtual Routing and Forwarding) interface, even if "vrf-also" is not used.

Description of the vulnerability

The Cisco Unified MeetingPlace Web Conferencing product uses a database.

However, HTTP POST parameters are directly injected in SQL queries, and sent to the database.

An attacker can therefore generate a SQL injection in Cisco Unified MeetingPlace Web Conferencing, in order to read or alter data.

computer vulnerability note CVE-2012-0745

AIX: privilege elevation via LDAP

Synthesis of the vulnerability

When the Extended LDAP User Filtering feature is used, a local attacker can access to the account of another user.
Impacted products: AIX.
Severity: 2/4.
Consequences: administrator access/rights, privileged access/rights, user access/rights.
Provenance: user shell.
Creation date: 04/05/2012.
Identifiers: BID-53393, CERTA-2012-AVI-251, CVE-2012-0745, VIGILANCE-VUL-11579.

Description of the vulnerability

The /etc/security/ldap/ldap.cfg file indicates the Base Distinguished Names of users who are allowed to access to the system. For example:
  userbasedn: ou=people, cn=aixdata
The administrator can filter the list of allowed users (Extended LDAP User Filtering). For example:
  userbasedn: ou=people, cn=aixdata??(attribute=value)

However, when the filtering is enabled, the getpwnam() function, which returns the passwd structure associated to a user, can return data of another user. Applications calling getpwnam() can then allow access to an account which is different from the requested one.

When the Extended LDAP User Filtering feature is used, a local attacker can therefore access to the account of another user.

computer vulnerability bulletin CVE-2012-2313

Linux kernel: memory corruption via dl2k

Synthesis of the vulnerability

A local attacker can use an ioctl on the dl2k driver, to corrupt the memory, in order to create a denial of service and possibly to execute code.
Impacted products: Fedora, Linux, openSUSE, RHEL, SUSE Linux Enterprise Desktop, SLES.
Severity: 2/4.
Consequences: privileged access/rights.
Provenance: user shell.
Creation date: 04/05/2012.
Identifiers: BID-53965, CVE-2012-2313, FEDORA-2012-7538, FEDORA-2012-7594, openSUSE-SU-2014:0766-1, RHSA-2012:1174-01, RHSA-2012:1304-01, RHSA-2012:1481-01, RHSA-2012:1541-01, RHSA-2012:1589-01, SUSE-SU-2012:0689-1, SUSE-SU-2012:0736-1, SUSE-SU-2015:0812-1, VIGILANCE-VUL-11578.

Description of the vulnerability

The drivers/net/ethernet/dlink/dl2k.c file implements the driver for network devices of the family D-Link DL2000 Gigabit Ethernet.

When a user calls an ioctl on this driver, the rio_ioctl() function is called. However, some of these private ioctl (SIOCDEVPRIVATE) do not check if the user has the CAP_NET_ADMIN capability. For example, the "SIOCDEVPRIVATE + 2" ioctl calls the mii_write() function, which changes a writing memory address.

A local attacker can therefore use an ioctl on the dl2k driver, to corrupt the memory, in order to create a denial of service and possibly to execute code.
