CVE-2018-1843
Description
The Identity and Access Management (IAM) services (IBM Cloud Private 3.1.0) do not use a secure channel, such as SSL, to exchange information only when accessed internally from within the cluster. It could be possible for an attacker with access to network traffic to sniff packets from the connection and uncover data. IBM X-Force ID: 150903
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
IBM Cloud Private 3.1.0 IAM services transmit data unencrypted internally, allowing network sniffing of sensitive information.
Vulnerability
The Identity and Access Management (IAM) services in IBM Cloud Private 3.1.0 do not use a secure channel, such as SSL, to exchange information when accessed internally within the cluster. This means that data transmitted between IAM components inside the cluster is sent in plaintext. [1]
Exploitation
An attacker with access to the cluster network traffic can sniff packets from the IAM service connections. No authentication or user interaction is required beyond network proximity. The attacker can capture and uncover sensitive data transmitted by the IAM services. [1]
Impact
Successful exploitation results in the disclosure of sensitive information transmitted by IAM services, compromising the confidentiality of data. The CVSS base score for this vulnerability is 4.1 (medium). [1]
Mitigation
The fixed version is IBM Cloud Private 3.1.1. Users should upgrade to this version. As a workaround, IPsec may be enabled to secure communications between cluster nodes. Refer to IBM Knowledge Center for guidance on encrypting cluster data network traffic with IPsec. [1]
