Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Restrict access to HCL Aftermarket DPC interfaces to trusted users and networks only, using network segmentation and firewall rules to limit exposure.
Monitor and audit logs for unusual access patterns or attempts to extract internal network information.
Educate users to be cautious about interacting with unsolicited or suspicious content that could trigger the vulnerability.
Implement strict input validation and error handling to prevent leakage of internal IP addresses through error messages or debug outputs.
Apply network-level protections such as Intrusion Detection/Prevention Systems (IDS/IPS) to detect reconnaissance activities.
Engage with HCL support channels to obtain patches or updates addressing this vulnerability as they become available.
Conduct regular vulnerability assessments and penetration testing to identify and remediate information disclosure issues proactively.
Use network address translation (NAT) and other obfuscation techniques to minimize exposure of internal IP addresses externally.
Consider deploying web application firewalls (WAF) or reverse proxies that can mask backend network details.
Maintain an incident response plan that includes procedures for handling information disclosure vulnerabilities and subsequent reconnaissance attempts.

Description

HCL Aftermarket DPC is affected by Internal IP Disclosure vulnerability will give attackers a clearer map of the organization’s network layout.

Impact

The primary impact of CVE-2025-55276 is the exposure of internal IP addresses, which can aid attackers in understanding the internal network architecture of affected organizations. While this does not directly lead to data breaches or system compromise, it significantly enhances the attacker's ability to conduct targeted reconnaissance and plan more effective attacks such as lateral movement, privilege escalation, or exploitation of other vulnerabilities. For organizations, this can increase the risk of subsequent, more damaging intrusions. The low CVSS score reflects the limited immediate damage, but the strategic value of the leaked information should not be underestimated, especially in high-security environments. The vulnerability could be exploited by remote attackers who trick users into interacting with malicious content, potentially leading to network mapping without requiring authentication. This can be particularly concerning for organizations with sensitive or critical infrastructure relying on HCL Aftermarket DPC, as attackers may use the disclosed information to bypass perimeter defenses or identify weak points in the network. Overall, the impact is indirect but can contribute to a larger attack chain if combined with other vulnerabilities or misconfigurations.
