EUVDB-ID: #VU13993
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-8037
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to improper handling of connection closures by the non-blocking I/O (NIO) and NIO2 connectors. A remote unauthenticated attacker can send a specially crafted request that submits malicious input, trigger bug in the tracking of connection closures, reuse user sessions in a new connection and access arbitrary data.
MitigationUpdate the affected packages.
