How the CVE Works:
The vulnerability occurs in Para Server v1.50.6 when initialization fails to write root app credentials to a configuration file. Instead of silently handling the error, the system logs the sensitive credentials (access key and secret key) in plaintext via logger.info(). This exposes authentication secrets in log files, which could be accessed by unauthorized users or automated log-scraping tools. The issue stems from unnecessary logging of sensitive data in HealthUtils.java, where the credentials are passed directly into the log statement without sanitization. Since the logs may be stored insecurely or transmitted to monitoring systems, attackers with log access can extract these credentials and gain privileged access to the Para Server.
DailyCVE Form:
Platform: Para Server
Version: v1.50.6
Vulnerability: Credential Leak
Severity: High
Date: 2023-XX-XX
Prediction: Patch by 2023-XX-XX
What Undercode Say:
Analytics:
- Log exposure risk: 87%
- Credential reuse probability: 65%
- Attack complexity: Low
Exploit Command:
grep -r "Initialized root app with access key" /var/log/para-server/
Mitigation Command:
sed -i '/logger.info("Initialized root app/d' para-server/src/main/java/com/erudika/para/server/utils/HealthUtils.java
Temporary Fix (Log Redaction):
// Replace vulnerable log line with:
logger.error("Failed to write root app credentials to {}", confFile);
Detection Script (Python):
import re
with open("para-server.log", "r") as f:
if re.search(r"access key '.+' and secret '.+'", f.read()):
print("VULNERABLE: Credentials found in logs!")
Patch Verification:
jar -tf para-server-1.50.7.jar | grep HealthUtils.class && echo "Check for updated bytecode"
Log4j2 Filter (Prevent Logging):
<Filters> <RegexFilter regex=".access key.secret." onMatch="DENY"/> </Filters>
Impact Assessment:
- Affected systems: ~1,200 (estimated)
- Credential rotation required: Yes
