Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy normalization. Specially crafted WS-Policy documents can trigger an exponential Cartesian cross-product expansion during the normalization process, causing unbounded memory allocation that exhausts the JVM heap. This occurs when the normalization process generates an excessive number of policy alternatives without bounds, leading to runtime memory exhaustion. Users should upgrade to 3.2.2 which limits the maximum number of normalized policy alternatives.

The versions of Primavera Unifier installed on the remote host are affected by multiple vulnerabilities as referenced in the July 2026 CPU advisory.

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component:
    Integration (Lodash)). Supported versions that are affected are 21.12.0-21.12.17, 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.14 and 25.12.0-25.12.6. Easily exploitable vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks     of this vulnerability can result in takeover of Primavera Unifier. (CVE-2026-4800)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component:
    Integration (Apache ZooKeeper)). Supported versions that are affected are 21.12.0-21.12.17,     22.12.0-22.12.15, 23.12.0-23.12.16, 24.12.0-24.12.14 and 25.12.0-25.12.6. Easily exploitable vulnerability     allows unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful     attacks of this vulnerability can result in unauthorized access to critical data or complete access to all     Primavera Unifier accessible data. (CVE-2026-24308)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Platform     (Apache Log4j)). Supported versions that are affected are 21.12.0-21.12.17, 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.14 and 25.12.0-25.12.6. Easily exploitable vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks     of this vulnerability can result in unauthorized creation, deletion or modification access to critical data     or all Primavera Unifier accessible data. (CVE-2026-34481)

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