Summary

An issue was discovered in Qualys Cloud Agent 4.8.0-49. It writes "ps auxwwe" output to the /var/log/qualys/qualys-cloud-agent-scan.log file. This may, for example, unexpectedly write credentials (from environment variables) to disk in cleartext. NOTE: there are no common circumstances in which qualys-cloud-agent-scan.log can be read by a user other than root; however, the file contents could be exposed through site-specific operational practices. The vendor does NOT characterize this as a vulnerability because the ps data collection is intentional, and would only capture credentials on a machine that was already affected by the CWE-214 weakness

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fuzzing and observing application log data/errors for application mapping
    An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.
