FAQ
Latest Global CVEs
An authentication bypass vulnerability exists in certain releases of Ciena Navigator Network Control Suite (NCS), Manage Control Plan (MCP), and Blue Planet products. The issue is caused by improper handling of HTTP request paths and headers, which allows an unauthenticated attacker to manipulate requests in a manner that bypasses authentication and associated audit logging controls.
In Ciena's Navigator Network Control Suite (NCS) and Manage Control Plan (MCP), there are hidden system accounts used for internal software operations. Some of these accounts have default passwords that may be predictable. While these accounts have very limited permissions on their own, an attacker could combine an attack using one of these accounts with other potential weaknesses to launch a more significant attack, possibly leading to escalation of privilege on the system.
Buffer Overflow vulnerability in OpenHTJ2K v.0.18.4 and before allows an attacker to execute arbitrary code via the openhtj2k_decoder_impl::invoke, invoke_line_based, invoke_line_based_stream, and invoke_line_based_predecoded function in source/core/interface/decoder.cpp
Buffer Overflow vulnerability in OpenHTJ2K v.0.18.4 and before allows an attacker to execute arbitrary code via the j2k_precinct_subband::parse_packet_header() in source/core/coding/coding_units.cpp
