Improper Restriction of Operations within the Bounds of a Memory Buffer in NetScaler ADC and NetScaler Gateway allows Unauthenticated Denial of Service and Out-Of-Bounds Memory Read

CVE-2023-6549 is a vulnerability classified under CWE-119, indicating improper restriction of operations within the bounds of a memory buffer in Cloud Software Group's NetScaler ADC and NetScaler Gateway products. The flaw exists in multiple product versions, including 12.1-FIPS, 12.1-NDcPP, 13.0, 13.1, 13.1-FIPS, and 14.1. This vulnerability allows an unauthenticated attacker to perform out-of-bounds memory reads and cause denial of service (DoS) conditions remotely without requiring any user interaction. The root cause is a failure to properly validate or restrict memory buffer operations, which can lead to memory corruption or leakage of sensitive information. The CVSS v3.1 score is 8.2 (high), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H, indicating network attack vector, low attack complexity, no privileges or user interaction required, no confidentiality impact, but integrity and availability impacts present. The vulnerability affects critical network infrastructure components that provide application delivery and secure gateway functions, making exploitation potentially disruptive. No public exploits have been reported yet, but the risk remains significant due to the ease of exploitation and critical nature of the affected products. The lack of available patches at the time of publication necessitates immediate attention to mitigation strategies.
