The version of F5 Networks BIG-IP installed on the remote host is prior to 16.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the K57542514 advisory.

    Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding     (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials,     cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit,     urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate     cookies or authentication data and send that information to a different host than when parsed correctly.
    This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8,     v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1;
    v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1,     v3.7.8, v3.7.8rc1, v3.7.9.(CVE-2019-9636)A security regression of CVE-2019-9636 was discovered in python     since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from     v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and     password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication     credentials, or other kind of information, it is possible for an attacker to provide specially crafted     URLs to make the application locate host-related information (e.g. cookies, authentication data) and send     them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of     an attack may vary based on the application.(CVE-2019-10160)ImpactA remote attacker may be able to use a     specially crafted URL to locate cookies or authentication data and send that information to a different     host than when parsed correctly.BIG-IP Extended Application Verification (EAV) monitors using the     Pythonurlsplit()function with URLs from an untrusted source may be impacted by this vulnerability.

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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

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

  - Python is an interpreted, interactive, object-oriented     programming language, which includes modules, classes,     exceptions, very high level dynamic data types and     dynamic typing. Python supports interfaces to many     system calls and libraries, as well as to various     windowing systems.Security Fix(es):A security     regression of CVE-2019-9636 was discovered in python,     since commit d537ab0ff9767ef024f26246899728f0116b1ec3,     which still allows an attacker to exploit CVE-2019-9636     by abusing the user and password parts of a URL. When     an application parses user-supplied URLs to store     cookies, authentication credentials, or other kind of     information, it is possible for an attacker to provide     specially crafted URLs to make the application locate     host-related information (e.g. cookies, authentication     data) and send them to a different host than where it     should, unlike if the URLs had been correctly parsed.
    The result of an attack may vary based on the     application.(CVE-2019-10160)urllib in Python 2.x     through 2.7.16 supports the local_file: scheme, which     makes it easier for remote attackers to bypass     protection mechanisms that blacklist file: URIs, as     demonstrated by triggering a     urllib.urlopen('local_file:///etc/passwd')     call.(CVE-2019-9948)Python's elementtree C accelerator     failed to initialise Expat's hash salt during     initialization. This could make it easy to conduct     denial of service attacks against Expat by constructing     an XML document that would cause pathological hash     collisions in Expat's internal data structures,     consuming large amounts CPU and     RAM.(CVE-2018-14647)python 2.7.14 is vulnerable to a     Heap-Buffer-Overflow as well as a Heap-Use-After-Free.
    Python versions prior to 2.7.14 may also be vulnerable     and it appears that Python 2.7.17 and prior may also be     vulnerable however this has not been confirmed. The     vulnerability lies when multiply threads are handling     large amounts of data. In both cases there is     essentially a race condition that occurs. For the     Heap-Buffer-Overflow, Thread 2 is creating the size for     a buffer, but Thread1 is already writing to the buffer     without knowing how much to write. So when a large     amount of data is being processed, it is very easy to     cause memory corruption using a Heap-Buffer-Overflow.
    As for the Use-After-Free,     Thread3-i1/4zMalloc-i1/4zThread1-i1/4zFree's-i1/4zThread2-Re-us     es-Free'd Memory. The PSRT has stated that this is not     a security vulnerability due to the fact that the     attacker must be able to run code, however in some     situations, such as function as a service, this     vulnerability can potentially be used by an attacker to     violate a trust boundary, as such the DWF feels this     issue deserves a CVE.(CVE-2018-1000030)
