The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2023:0053 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2020-10735:
    A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when     using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for     1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not     affected). The highest threat from this vulnerability is to system availability.

    CVE-2021-28861:
    ** DISPUTED ** Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to     no protection against multiple (/) at the beginning of URI path which may leads to information disclosure.
    NOTE: this is disputed by a third party because the http.server.html documentation page states Warning:
    http.server is not recommended for production. It only implements basic security checks.

    CVE-2022-45061:
    An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path     when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name     being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by     remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger     excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
    For example, the attack payload could be placed in the Location header of an HTTP response with status     code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16.

    CVE-2023-24329:
    An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting     methods by supplying a URL that starts with blank characters.

    Package        : python2.7     Version        : 2.7.16-2+deb10u3     CVE ID         : CVE-2021-23336 CVE-2022-0391 CVE-2022-48560 CVE-2022-48565                      CVE-2022-48566 CVE-2023-24329 CVE-2023-40217

    This update fixes multiple vulnerabilities concerning the urlparse module as     well as vulnerabilities concerning the heapq, hmac, plistlib and ssl modules.

    CVE-2021-23336

        Python was vulnerable to Web Cache Poisoning via urlparse.parse_qsl and         urlparse.parse_qs by using a vector called parameter cloaking. When the         attacker can separate query parameters using a semicolon (;), they can         cause a difference in the interpretation of the request between the proxy         (running with default configuration) and the server. This can result in         malicious requests being cached as completely safe ones, as the proxy would         usually not see the semicolon as a separator, and therefore would not         include it in a cache key of an unkeyed parameter.

    CVE-2022-0391

        The urlparse module helps break Uniform Resource Locator (URL) strings into         components. The issue involves how the urlparse method does not sanitize         input and allows characters like '\r' and '\n' in the URL path.  This flaw         allows an attacker to input a crafted URL, leading to injection attacks.

    CVE-2022-48560

        A use-after-free exists in Python via heappushpop in heapq.

    CVE-2022-48565

        An XML External Entity (XXE) issue was discovered in Python.  The plistlib         module no longer accepts entity declarations in XML plist files to avoid         XML vulnerabilities.

    CVE-2022-48566

        An issue was discovered in compare_digest in Lib/hmac.py in Python.
        Constant-time-defeating optimisations were possible in the accumulator         variable in hmac.compare_digest.

    CVE-2023-24329

        An issue in the urlparse component of Python allows attackers to bypass         blocklisting methods by supplying a URL that starts with blank characters.

    CVE-2023-40217

        The issue primarily affects servers written in Python (such as HTTP         servers) that use TLS client authentication. If a TLS server-side socket is         created, receives data into the socket buffer, and then is closed quickly,         there is a brief window where the SSLSocket instance will detect the socket         as not connected and won't initiate a handshake, but buffered data will         still be readable from the socket buffer.  This data will not be         authenticated if the server-side TLS peer is expecting client certificate         authentication, and is indistinguishable from valid TLS stream data. Data         is limited in size to the amount that will fit in the buffer. (The TLS         connection cannot directly be used for data exfiltration because the         vulnerable code path requires that the connection be closed on         initialization of the SSLSocket.)


    For Debian 10 buster, these problems have been fixed in version     2.7.16-2+deb10u3.

    We recommend that you upgrade your python2.7 packages.

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 AHV installed on the remote host is prior to 20220304.423. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.423 advisory.

  - An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory     writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110,     Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-0767)

  - An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting     methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

  - There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
    X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME     incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently     interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL     checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may     allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or     enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate     chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these     inputs, the other input must already contain an X.400 address as a CRL distribution point, which is     uncommon. As such, this vulnerability is most likely to only affect applications which have implemented     their own functionality for retrieving CRLs over a network. (CVE-2023-0286)

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2957-1 advisory.

    Update to 3.9.17:

    - urllib.parse.urlsplit() now strips leading C0 control and space       characters following the specification for URLs defined by WHATWG in       response to CVE-2023-24329 (bsc#1208471).
    - Fixed a security in flaw in uu.decode() that could allow for directory       traversal based on the input if no out_file was specified.
    - Do not expose the local on-disk location in directory indexes produced by       http.client.SimpleHTTPRequestHandler.
    - trace.__main__ now uses io.open_code() for files       to be executed instead of raw open().
    - CVE-2007-4559: The extraction methods in tarfile, and shutil.unpack_archive(), have       a new filter argument that allows limiting tar features than may be       surprising or dangerous, such as creating files outside the destination       directory. See Extraction filters for details (fixing bsc#1203750).
    - Fixed a deadlock at shutdown when clearing thread states if any       finalizer tries to acquire the runtime head lock.
    - Fixed a crash due to a race while iterating over thread states in       clearing threading.local.
