It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-046 advisory.

  • Acceptance of some invalid Transfer-Encoding headers in the HTTP/1 client in net/http before Go 1.17.12 and Go 1.18.4 allows HTTP request smuggling if combined with an intermediate server that also improperly fails to reject the header as invalid. (CVE-2022-1705)

  • Uncontrolled recursion in the Parse functions in go/parser before Go 1.17.12 and Go 1.18.4 allow an attacker to cause a panic due to stack exhaustion via deeply nested types or declarations. (CVE-2022-1962)

  • Authorization Bypass Through User-Controlled Key in GitHub repository emicklei/go-restful prior to v3.8.0.
    (CVE-2022-1996)

  • encoding/pem in Go before 1.17.9 and 1.18.x before 1.18.1 has a Decode stack overflow via a large amount of PEM data. (CVE-2022-24675)

  • The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey. (CVE-2022-27191)

  • Uncontrolled recursion in Decoder.Skip in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via a deeply nested XML document. (CVE-2022-28131)

  • The generic P-256 feature in crypto/elliptic in Go before 1.17.9 and 1.18.x before 1.18.1 allows a panic via long scalar input. (CVE-2022-28327)

  • Reader.Read does not set a limit on the maximum size of file headers. A maliciously crafted archive could cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panics.
    After fix, Reader.Read limits the maximum size of header blocks to 1 MiB. (CVE-2022-2879)

  • Go before 1.17.10 and 1.18.x before 1.18.2 has Incorrect Privilege Assignment. When called with a non-zero flags parameter, the Faccessat function could incorrectly report that a file is accessible.
    (CVE-2022-29526)

  • Non-random values for ticket_age_add in session tickets in crypto/tls before Go 1.17.11 and Go 1.18.3 allow an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket ages during session resumption. (CVE-2022-30629)

  • Uncontrolled recursion in Glob in io/fs before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via a path which contains a large number of path separators.
    (CVE-2022-30630)

  • Uncontrolled recursion in Reader.Read in compress/gzip before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via an archive containing a large number of concatenated 0-length compressed files. (CVE-2022-30631)

  • Uncontrolled recursion in Glob in path/filepath before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via a path containing a large number of path separators.
    (CVE-2022-30632)

  • Uncontrolled recursion in Unmarshal in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via unmarshalling an XML document into a Go struct which has a nested field that uses the ‘any’ field tag. (CVE-2022-30633)

  • Uncontrolled recursion in Decoder.Decode in encoding/gob before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via a message which contains deeply nested structures.
    (CVE-2022-30635)

  • Improper exposure of client IP addresses in net/http before Go 1.17.12 and Go 1.18.4 can be triggered by calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the X-Forwarded-For header, which causes ReverseProxy to set the client IP as the value of the X-Forwarded-For header. (CVE-2022-32148)

  • Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion or denial of service. The parsed regexp representation is linear in the size of the input, but in some cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Normal use of regular expressions is unaffected. (CVE-2022-41715)

  • Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows.
    In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string A=B\x00C=D sets the variables A=B and C=D. (CVE-2022-41716)

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