A WebFlux application with a compromised subdomain (for example, compromised via cross-site scripting (XSS)) is vulnerable to an escalation attack exchanging a known session ID for that of an authenticated user. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.

The version of IBM Engineering Requirements Management DOORS (formerly IBM Rational DOORS) installed on the remote host is 9.6.1.1 prior or equal to 9.6.1.13 or 9.7.2.1 prior or equal to 9.7.2.11. It is, therefore, affected by multiple vulnerabilities as referenced in the 7279145 advisory.

  - IBM DOORS Web Access do not limit the length of a connection which could allow for a Slowloris HTTP denial     of service attack to take place. This can cause the web server to become unresponsive. (CVE-2024-25039)

  - IBM DOORS Web Access is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated     attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality     potentially leading to credentials disclosure within a trusted session. (CVE-2025-0152)

  - IBM DOORS Web Access could allow a remote attacker to obtain sensitive information when a detailed     technical error message is returned in the browser. This information could be used in further attacks     against the system. (CVE-2020-4984)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A WebFlux application with a compromised subdomain (for example, compromised via cross-site scripting
    (XSS)) is vulnerable to an escalation attack exchanging a known session ID for that of an authenticated
    user. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27;
    5.3.0 through 5.3.48. (CVE-2026-41839)

The version of Spring Framework installed on the remote host is 5.3.x prior to 5.3.49, 6.1.x prior to 6.1.28, 6.2.x prior to 6.2.18.1, or 7.0.x prior to 7.0.7.1. It is, therefore, affected by multiple vulnerabilities:

  - IDs for WebSocket sessions in the spring-websocket module are not cryptographically unpredictable, which may be     possible to exploit in combination with inadequate authorization rules. (CVE-2026-41838)

  - Applications may be vulnerable to a Regular Expression Denial of Service (ReDoS) attack if an attacker is able to     provide a pattern which is then directly or indirectly supplied to one of the following methods in AntPathMatcher:
    match, matchStart, extractUriTemplateVariables. (CVE-2026-41848)

  - In an untrusted JMS environment, org.springframework.jms.support.converter.MappingJackson2MessageConverter and     org.springframework.jms.support.converter.JacksonJsonMessageConverter allow arbitrary class instantiation, which     can lead to unauthorized actions via gadget class deserialization. (CVE-2026-41855)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A WebFlux application with a compromised subdomain (for example, compromised via cross-site scripting     (XSS)) is vulnerable to an escalation attack exchanging a known session ID for that of an authenticated     user. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27;
    5.3.0 through 5.3.48. (CVE-2026-41839)

Note that Nessus relies on the presence of the package as reported by the vendor.
