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: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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

1. Implement strict URL validation and sanitization on the 'nhl' parameter within Newforma Project Center if possible, or request a patch from the vendor as soon as it becomes available. 2. Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious redirect attempts involving the vulnerable endpoint. 3. Educate users and employees about the risks of clicking on unexpected or suspicious links, especially those appearing to originate from internal project management tools. 4. Use email and web filtering solutions to detect and block phishing attempts that leverage the open redirect vulnerability. 5. Monitor logs for unusual redirect URL patterns or spikes in traffic to the vulnerable endpoint. 6. Consider network-level controls to restrict outbound connections to untrusted domains from user workstations. 7. Coordinate with Newforma support and subscribe to vendor advisories to receive updates on patches or workarounds. 8. If feasible, temporarily disable or restrict access to the '/DownloadWeb/hyperlinkredirect.aspx' endpoint until a fix is applied.

Description

CVE-2025-35059 is an open redirect vulnerability in Newforma Project Center's Info Exchange component, specifically in the '/DownloadWeb/hyperlinkredirect.aspx' endpoint. The vulnerability allows unauthenticated attackers to craft URLs with the 'nhl' parameter that redirect users to untrusted external sites. This can facilitate phishing attacks or redirect users to malicious domains. The vulnerability has a CVSS score of 4.3 (medium severity), requires no authentication, but does require user interaction to follow the malicious link. There is no known exploit in the wild and no patches currently available. The impact primarily affects user trust and integrity rather than confidentiality or availability. European organizations using Newforma Project Center should be cautious, especially those in construction and project management sectors where this software is used. Mitigations include user education, monitoring for suspicious URLs, and implementing web filtering or URL validation at the application or network level.

Impact

For European organizations, the primary impact of CVE-2025-35059 is the potential for social engineering and phishing attacks leveraging trusted Newforma URLs to redirect users to malicious sites. This can lead to credential theft, malware infections, or further exploitation via drive-by downloads. Although the vulnerability does not directly expose sensitive data or disrupt service availability, the loss of user trust and the risk of secondary attacks can have significant operational and reputational consequences. Organizations relying on Newforma Project Center for project collaboration and document management may see increased risk of targeted phishing campaigns against employees, contractors, or partners. The medium severity rating reflects that the vulnerability is not critical but still poses a meaningful risk, especially in environments where users may be less security-aware or where phishing defenses are weak. The lack of authentication requirement means attackers can exploit this vulnerability externally without insider access. The absence of known exploits in the wild provides a window for mitigation before active exploitation occurs.

CWE-601URL Redirection to Untrusted Site ('Open Redirect') (opens in a new tab)
Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
