Rankiteo Explanation
Attack threatening the organization's existence
Description: Email marketing firm Klaviyo suffered a data breach in August 2022 after hackers gained access to internal systems after stealing an employee's credentials via a phishing attack. The threat actors downloaded marketing lists for cryptocurrency-related customers including names, addresses, emails, and phone numbers. They also used internal customer support tools to search for primarily crypto-related accounts and viewed list and segment information for 44 Klaviyo accounts. Klaviyo immediately notified law enforcement and engaged with a third-party cybersecurity firm to investigate a breach of their network.

Description
KEDA is a Kubernetes-based Event Driven Autoscaling component. Prior to versions 2.17.3 and 2.18.3, an Arbitrary File Read vulnerability has been identified in KEDA, potentially affecting any KEDA resource that uses TriggerAuthentication to configure HashiCorp Vault authentication. The vulnerability stems from an incorrect or insufficient path validation when loading the Service Account Token specified in spec.hashiCorpVault.credential.serviceAccount. An attacker with permissions to create or modify a TriggerAuthentication resource can exfiltrate the content of any file from the node's filesystem (where the KEDA pod resides) by directing the file's content to a server under their control, as part of the Vault authentication request. The potential impact includes the exfiltration of sensitive system information, such as secrets, keys, or the content of files like /etc/passwd. This issue has been patched in versions 2.17.3 and 2.18.3.
