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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: Present: The successful attack depends on the presence of specific deployment and execution conditions of the vulnerable system that enable the attack. These include: a race condition must be won to successfully exploit the vulnerability (the successfulness of the attack is conditioned on execution conditions that are not under full control of the attacker, or the attack may need to be launched multiple times against a single target before being successful); the attacker must inject themselves into the logical network path between the target and the resource requested by the victim (e.g. vulnerabilities requiring an on-path attacker).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

To mitigate CVE-2025-35058, European organizations should implement the following specific measures: 1) Immediately restrict outbound SMB (ports 445 and 139) traffic from the Newforma Project Center NIX server to only trusted internal systems, blocking any connections to external or untrusted IP addresses. 2) Monitor network traffic for unusual SMB connection attempts originating from the NIX server, using intrusion detection systems or network monitoring tools to detect potential exploitation attempts. 3) Employ SMB signing and enforce strong authentication policies to reduce the risk of NTLM relay attacks. 4) Isolate the NIX server within a segmented network zone with strict access controls to limit exposure. 5) Regularly audit service account usage and rotate credentials to minimize the window of opportunity for attackers. 6) Engage with Newforma for any available patches or updates and apply them promptly once released. 7) Educate IT and security teams about this vulnerability to ensure rapid detection and response. 8) Consider deploying endpoint detection and response (EDR) solutions on the NIX server to identify suspicious activities related to SMB connections or credential theft.

Description

CVE-2025-35058 is a high-severity authentication bypass vulnerability in Newforma Project Center's Info Exchange (NIX) component. It allows a remote, unauthenticated attacker to trigger the NIX server to initiate an SMB connection to an attacker-controlled system, capturing the NTLMv2 hash of the service account used by NIX. This vulnerability stems from improper authentication validation (CWE-294) and does not require user interaction or prior authentication. Exploitation can lead to credential theft, enabling lateral movement or privilege escalation within affected environments. No known exploits are currently reported in the wild, but the vulnerability's nature and CVSS score of 8.2 indicate significant risk. European organizations using Newforma Project Center should prioritize patching or mitigating this issue to prevent potential compromise. Countries with strong adoption of Newforma products, especially in construction and project management sectors, are at higher risk. Immediate mitigation includes network segmentation, SMB traffic monitoring, and restricting outbound SMB connections from the NIX server.

Impact

For European organizations, the impact of CVE-2025-35058 can be substantial. The theft of NTLMv2 hashes of service accounts used by Newforma Project Center can lead to unauthorized access to sensitive project data, intellectual property, and internal communications. Given that Newforma Project Center is widely used in architecture, engineering, and construction industries, compromised credentials could facilitate espionage, data exfiltration, or disruption of critical project workflows. The vulnerability's ability to be exploited remotely without authentication increases the risk of widespread attacks, especially in environments where the NIX server is exposed or insufficiently segmented. Additionally, attackers leveraging captured hashes may move laterally within corporate networks, escalating privileges and potentially impacting other critical systems. This could result in operational downtime, financial losses, and reputational damage. The vulnerability also raises compliance concerns under GDPR if personal data is accessed or leaked due to exploitation. Organizations with interconnected SMB environments are particularly vulnerable to this type of attack vector.

Summary

CVE-2025-35058 is an authentication bypass vulnerability identified in Newforma Project Center's Info Exchange (NIX) component, specifically in the '/UserWeb/Common/MarkupServices.ashx' endpoint. This flaw allows a remote attacker, without any authentication, to coerce the NIX server into making an SMB connection to a system controlled by the attacker. During this forced connection, the attacker can capture the NTLMv2 hash of the NIX service account configured by the customer. The vulnerability is classified under CWE-294, indicating improper authentication mechanisms that fail to adequately verify the legitimacy of requests. The attack vector requires no user interaction and no privileges, making it easily exploitable remotely over the network. The captured NTLMv2 hash can be subjected to offline cracking attempts or relay attacks, potentially leading to unauthorized access or lateral movement within the victim's network. The CVSS 4.0 base score is 8.2, reflecting a high severity due to the ease of exploitation and the critical nature of credential compromise. Although no public exploits have been reported yet, the vulnerability poses a significant threat to organizations relying on Newforma Project Center for project management and collaboration. The lack of available patches at the time of publication necessitates immediate mitigation strategies to reduce exposure.

Base weaknessLikelihood of exploit: HighOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
Architecture and Design
Utilize some sequence or time stamping functionality along with a checksum which takes this into account in order to ensure that messages can be parsed only once.
Architecture and Design
Since any attacker who can listen to traffic can see sequence numbers, it is necessary to sign messages with some kind of cryptography to ensure that sequence numbers are not simply doctored along with content.
