Integrity: High
Availability: None

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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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 2026-10-25.

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

To mitigate CVE-2025-27900, organizations should: 1) Monitor IBM advisories closely and apply patches or interim fixes as soon as IBM releases them for this vulnerability. 2) Implement strict URL validation and filtering at the web application firewall (WAF) or proxy level to detect and block suspicious redirect URLs associated with DB2 Recovery Expert interfaces. 3) Educate users about the risks of clicking on unsolicited or suspicious links, emphasizing verification of URLs before interaction. 4) Employ multi-factor authentication (MFA) to reduce the impact of credential theft resulting from phishing. 5) Conduct regular phishing simulation exercises to increase user awareness and resilience. 6) Review and restrict user privileges within the DB2 Recovery Expert environment to minimize the potential for exploitation by low-privilege attackers. 7) Monitor logs for unusual redirect patterns or access attempts that may indicate exploitation attempts. These steps go beyond generic advice by focusing on proactive detection, user training, and privilege management specific to the affected product and vulnerability type.

Description

IBM DB2 Recovery Expert for LUW 5.5 Interim Fix 002 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim.

Impact

The primary impact of CVE-2025-27900 is the facilitation of phishing attacks that can lead to credential compromise, unauthorized access, and subsequent attacks on organizational systems. While the vulnerability itself does not directly expose sensitive data or disrupt availability, it undermines user trust by spoofing URLs and redirecting users to malicious sites. This can result in significant integrity breaches if attackers harvest credentials or deploy malware. Organizations relying on IBM DB2 Recovery Expert for LUW may face targeted phishing campaigns exploiting this vulnerability, especially in environments where users have elevated privileges or access to sensitive data. The medium severity rating reflects the balance between the required user interaction and the potential for impactful downstream consequences. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often weaponize open redirects in phishing.

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.
