A vulnerability has been found in Cisco FXOS and NX-OS (Router Operating System) (the affected version unknown) and classified as problematic. Affected by this vulnerability is an unknown part of the component LDAP. The manipulation as part of a Basic Encoding Rule leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. As an impact it is known to affect availability. The summary by CVE is:
Multiple vulnerabilities in the implementation of the Lightweight Directory Access Protocol (LDAP) feature in Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to the improper parsing of LDAP packets by an affected device. An attacker could exploit these vulnerabilities by sending an LDAP packet crafted using Basic Encoding Rules (BER) to an affected device. The LDAP packet must have a source IP address of an LDAP server configured on the targeted device. A successful exploit could cause the affected device to reload, resulting in a DoS condition.
