Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: BMC Control-M fails to stop validating client certificates when a **NULL byte** is found in the email address field.β¦
π¦ **Affected**: **BMC Control-M**. Specifically versions **9.0.18 through 9.0.20**. If you are running any version in this range, you are vulnerable. π **Published**: 2025-09-16.
Q4What can hackers do? (Privileges/Data)
π» **Attacker Capabilities**: By bypassing ACLs, hackers can potentially achieve **High Impact** on Confidentiality, Integrity, and Availability (CVSS: H/H/H).β¦
βοΈ **Exploitation Threshold**: **High Complexity (AC:H)**. While no authentication is required (PR:N), the attack requires specific conditions (NULL byte injection in email field) to succeed.β¦
π **Public Exploit**: **No**. The `pocs` field is empty. There are currently no public Proof-of-Concept (PoC) scripts or widespread wild exploitation reported. However, the risk remains due to the severity of the flaw.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: 1. Check your Control-M version (is it 9.0.18-9.0.20?). 2. Review logs for unusual certificate validation errors or NULL byte anomalies. 3.β¦
π οΈ **Official Fix**: **Yes**. BMC has released advisories. Refer to the vendor links provided (Knowledge Articles 000441967 & 000442099) for official patching instructions and mitigation steps.
