websocket-extensions npm module prior to 0.1.4 allows Denial of Service (DoS) via Regex Backtracking. The extension parser may take quadratic time when parsing a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. This could be abused by an attacker to conduct Regex Denial Of Service (ReDoS) on a single-threaded server by providing a malicious payload with the Sec-WebSocket-Extensions header.

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

  - websocket-extensions npm module prior to 0.1.4 allows Denial of Service (DoS) via Regex Backtracking. The
    extension parser may take quadratic time when parsing a header containing an unclosed string parameter
    value whose content is a repeating two-byte sequence of a backslash and some other character. This could
    be abused by an attacker to conduct Regex Denial Of Service (ReDoS) on a single-threaded server by
    providing a malicious payload with the Sec-WebSocket-Extensions header. (CVE-2020-7662)

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2023-0613 advisory.

  - A prototype pollution vulnerability exists in the function copy in dom.js in the xmldom (published as     @xmldom/xmldom) package before 0.8.3 for Node.js via the p variable. NOTE: the vendor states we are in     the process of marking this report as invalid; however, some third parties takes the position that A     prototype injection/Prototype pollution is not just when global objects are polluted with recursive merge     or deep cloning but also when a target object is polluted. (CVE-2022-37616)

  - When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by     finalizing the operation with a rename from a temporary name to the final target file name.In that rename     operation, it might accidentally *widen* the permissions for the target file, leaving the updated file     accessible to more users than intended. (CVE-2022-32207)

  - An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the     XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to     access an array at a negative 2GB offset, typically leading to a segmentation fault. (CVE-2022-40303)

  - An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a     hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be     provoked. (CVE-2022-40304)

  - 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)

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