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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to 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 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-2025-42924, European organizations should implement multiple layers of defense. First, monitor SAP security advisories closely and apply patches or updates from SAP as soon as they become available. In the absence of official patches, implement URL validation and filtering at the web application firewall (WAF) or proxy level to block suspicious redirection attempts. Educate employees and recruitment staff about the risks of clicking unsolicited or suspicious links, especially those purporting to be from SAP E-Recruiting portals. Employ email security solutions that detect and quarantine phishing attempts leveraging malicious URLs. Review and harden SAP E-Recruiting BSP configurations to restrict open redirect parameters if configurable. Enable logging and monitoring of redirection events within SAP to detect anomalous patterns. Consider implementing multi-factor authentication (MFA) for SAP access to reduce the impact of credential theft. Finally, conduct regular security awareness training focused on social engineering and phishing threats related to trusted enterprise applications.

Description

SAP S/4HANA landscape SAP E-Recruiting BSP allows an unauthenticated attacker to craft malicious links, when clicked the victim could be redirected to the page controlled by the attacker. This has low impact on confidentiality and integrity of the application with no impact on availability.

Impact

For European organizations, this vulnerability poses a moderate risk primarily through social engineering and phishing campaigns leveraging trusted SAP E-Recruiting URLs. Given the widespread use of SAP S/4HANA in large enterprises across Europe, especially in sectors like manufacturing, finance, and public administration, attackers could exploit this flaw to redirect employees or job applicants to malicious sites. This could lead to credential theft, malware infections, or reputational damage if users are compromised via these redirects. Although the direct impact on SAP system confidentiality and integrity is low, the indirect consequences through user compromise can be significant. The vulnerability does not affect system availability, so operational disruption is unlikely. However, the potential for targeted phishing attacks exploiting trusted SAP URLs is a concern, especially in countries with high SAP adoption and where SAP E-Recruiting is actively used for talent acquisition. Organizations handling sensitive personal data in recruitment processes must be vigilant to prevent data leakage or fraud stemming from redirected users.

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.
