An issue has been fixed in Qt versions 5.14.0 where QPluginLoader attempts to load plugins relative to the working directory, allowing attackers to execute arbitrary code via crafted files.

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

  - An issue has been fixed in Qt versions 5.14.0 where QPluginLoader attempts to load plugins relative to the     working directory, allowing attackers to execute arbitrary code via crafted files. (CVE-2020-24742)

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

According to the versions of the qt5-qtbase packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2020-0570. Reason: This candidate is a     duplicate of CVE-2020-0570. A typo caused the wrong ID to be used. Notes: All CVE users should reference     CVE-2020-0570 instead of this candidate. All references and descriptions in this candidate have been     removed to prevent accidental usage.

  - An issue has been fixed in Qt versions 5.14.0 where QPluginLoader attempts to load plugins relative to the     working directory, allowing attackers to execute arbitrary code via crafted files. (CVE-2020-24742)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of qt5-qtbase installed on the remote host is prior to 5.9.2-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1543 advisory.

    2023-08-03: CVE-2020-24742 was added to this advisory.

    Files placed by attacker can influence the working directory and lead to malicious code execution     (CVE-2020-0569)

    Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated     user to potentially enable elevation of privilege via local access. (CVE-2020-0570)

    An issue has been fixed in Qt versions 5.14.0 where QPluginLoader attempts to load plugins relative to the     working directory, allowing attackers to execute arbitrary code via crafted files. (CVE-2020-24742)

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

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