ESAPI (The OWASP Enterprise Security API) is a free, open source, web application security control library. Prior to version 2.3.0.0, the default implementation of `Validator.getValidDirectoryPath(String, String, File, boolean)` may incorrectly treat the tested input string as a child of the specified parent directory. This potentially could allow control-flow bypass checks to be defeated if an attack can specify the entire string representing the 'input' path. This vulnerability is patched in release 2.3.0.0 of ESAPI. As a workaround, it is possible to write one's own implementation of the Validator interface. However, maintainers do not recommend this.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8181-1 advisory.

    Jaroslav Lobaevski discovered that ESAPI incorrectly validated directory paths during path verification.
    An attacker could possibly use this issue to bypass directory validation checks, leading to control-flow     bypass. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04     LTS. (CVE-2022-23457)

    Kevin W. Wall and Sebastian Passaro discovered that ESAPI did not properly sanitize javascript URLs     because of an incorrect regular expression. An attacker could possibly use this issue to perform a cross-     site scripting attack. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and     Ubuntu 22.04 LTS. (CVE-2022-24891)

    Longlong Gong discovered that ESAPI did not properly neutralize special elements during SQL injection     defense. A remote attacker could possibly use this issue to perform SQL injection. (CVE-2025-5878)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-4246 advisory.

    Package        : libowasp-esapi-java     Version        : 2.4.0.0-0+deb11u1     CVE ID         : CVE-2022-23457 CVE-2022-24891 CVE-2025-5878     Debian Bug     : 1010339 1109378

    Several security vulnerabilities have been discovered in libowasp-esapi-java,     a Java Enterprise Security API.

    CVE-2022-23457:

        ESAPI (The OWASP Enterprise Security API) is a free, open source, web         application security control library. Prior to this update the default         implementation of `Validator.getValidDirectoryPath(String, String, File,         boolean)` may incorrectly treat the tested input string as a child of the         specified parent directory. This potentially could allow control-flow         bypass checks to be defeated if an attack can specify the entire string         representing the 'input' path.

    CVE-2022-24891:

        There is a potential for a cross-site scripting vulnerability in ESAPI         caused by a incorrect regular expression for onsiteURL in the
        **antisamy-esapi.xml** configuration file that can cause javascript: URLs         to fail to be correctly sanitized.

    CVE-2025-5878:

        This issue affects the interface Encoder.encodeForSQL of the         SQL Injection Defense. An attack leads to an improper neutralization of         special elements. We are not aware of any affected reverse-dependencies in         Debian but if you use ESAPI in a stand-alone project, you should be aware         that the Encoder.encodeForSQL method has been deprecated and will be         removed eventually. In addition the DB2Codec, MySQLCodec and OracleCodec         classes have been deprecated too. We recommend to carefully assess if         your project might be affected by these classes and methods and if you have         to implement additional steps to secure your application. The update does         not automatically protect you from any potential risks.

    For Debian 11 bullseye, these problems have been fixed in version     2.4.0.0-0+deb11u1.

    We recommend that you upgrade your libowasp-esapi-java packages.

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

  - ESAPI (The OWASP Enterprise Security API) is a free, open source, web application security control
    library. Prior to version 2.3.0.0, the default implementation of `Validator.getValidDirectoryPath(String,
    String, File, boolean)` may incorrectly treat the tested input string as a child of the specified parent
    directory. This potentially could allow control-flow bypass checks to be defeated if an attack can specify
    the entire string representing the 'input' path. This vulnerability is patched in release 2.3.0.0 of
    ESAPI. As a workaround, it is possible to write one's own implementation of the Validator interface.
    However, maintainers do not recommend this. (CVE-2022-23457)

The versions of Primavera Unifier installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2022 CPU advisory.

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Document     Management (Apache Solr)). Supported versions that are affected are 18.8, 19.12, 20.12 and 21.12. Easily     exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise     Primavera Unifier. Successful attacks of this vulnerability can result in takeover of Primavera Unifier.
    (CVE-2020-9492)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: User     Interface (Enterprise Security API)). Supported versions that are affected are 18.8, 19.12, 20.12 and     21.12. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to     compromise Primavera Unifier. Successful attacks of this vulnerability can result in takeover of Primavera     Unifier. (CVE-2022-23457)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: User     Interface (Moment.js)). Supported versions that are affected are 19.12, 20.12 and 21.12. Easily     exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise     Primavera Unifier.

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Document     Management (Apache Tika)). Supported versions that are affected are 18.8, 19.12, 20.12 and 21.12. Easily     exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Primavera     Unifier executes to compromise Primavera Unifier. Successful attacks require human interaction from a     person other than the attacker. Successful attacks of this vulnerability can result in unauthorized     ability to cause a partial denial of service (partial DOS) of Primavera Unifier.  (CVE-2022-33879)

  - Security-in-Depth issue in the Primavera Unifier product of Oracle Construction and Engineering     (component: Platform, User Interface (Apache Velocity Engine)). This vulnerability cannot be exploited     in the context of this product. (CVE-2020-13936)

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

The version of Oracle WebLogic Server installed on the remote host is missing a security patch from the July 2022 Critical Patch Update (CPU). It is, therefore, affected by multiple vulnerabilities, including:

  - Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Third Party     Tools, Samples (Spring Framework)). Supported versions that are affected are 12.2.1.3.0, 12.2.1.4.0 and     14.1.1.0.0.

Supported versions that are affected are 12.2.1.3.0,     12.2.1.4.0 and 14.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network     access via HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result     in takeover of Oracle WebLogic Server. (CVE-2022-23457)

  - Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Centralized     Third Party Jars (Apache Maven)). Supported versions that are affected are 12.2.1.3.0 and 12.2.1.4.0.

Successful attacks of this vulnerability can result in unauthorized     creation, deletion or modification access to critical data or all Oracle WebLogic Server accessible data     as well as unauthorized access to critical data or complete access to all Oracle WebLogic Server     accessible data. (CVE-2021-26291)
