| CVE-2017-5638 | Unauthenticated RCE in Apache Struts Jakarta Multipart parser CVE-2017-5638 is an improper input validation flaw (CWE-20) in the Jakarta Multipart parser of Apache Struts, in which the parser mishandles the Content-Type value of a file upload and allows malicious upload leading to remote code execution. It is triggered remotely without authentication by sending a crafted Content-Type header in a multipart request to a Struts endpoint; no valid upload or credentials are required. A successful attacker gains code execution in the security context of the application server, which typically enables host compromise, data theft, or ransomware deployment. Any organization running Apache Struts applications that use the Jakarta Multipart parser is affected; the provided data specifies only "Apache Struts" and gives no version ranges. Exploitation is confirmed in the wild: the flaw is listed in CISA KEV (added 2021-11-03) with known ransomware use, EPSS assigns it roughly a 100% exploitation probability (100th percentile), and no public PoC is catalogued in the source data. Do: Apply updates per vendor instructions: upgrade Apache Struts to the releases that fix this flaw (2.3.32 / 2.5.10.1 or later, per Apache advisory S2-045), and check for Struts jars bundled inside application packages and vendor appliances. Prioritize internet-facing apps, and as an interim mitigation validate or filter the Content-Type header on multipart requests. Because exploitation is in the wild and ransomware use is known, also review web and application server logs for evidence of successful compromise. | 9.8 | 100% | KEV ransomware PoC ×10 |

The results of the forensic investigation on the massive Equifax hack revealed additional 2.4 Million identities were involved in the security incident.
The massive Equifax hack made the headlines again, new revelations about the security breach emerge in the last hours.
The credit bureau company announced this week it identified an additional 2.4 million American consumers affected by 2017 hack.
In 2017 Equifax confirmed it has suffered a massive data breach, cyber criminals stole sensitive personal records of 145 million belonging to US citizens and hundreds of thousands Canada and in the UK.
Attackers exploited the CVE-2017-5638 Apache Struts vulnerability. The vulnerability affects the Jakarta Multipart parser upload function in Apache and could be exploited by an attacker to make a maliciously crafted request to an Apache web server.
The vulnerability was fixed back in March, but the company did not update its systems, the thesis was also reported by an Apache spokeswoman to the Reuters agency.
Compromised records include names, social security numbers, birth dates, home addresses, credit-score dispute forms, and for some users also the credit card numbers and driver license numbers.
A couple of weeks ago, experts argued the Equifax hack is worse than previously thought, according to documents provided by Equifax to the US Senate Banking Committee the attackers also stole taxpayer identification numbers, phone numbers, email addresses, and credit card expiry dates belonging to some Equifax customers.
Now the results of the forensic investigation revealed additional 2.4 Million identities were involved in the security incident.
“This is not about newly discovered stolen data,” explained Paulino do Rego Barros, ad interim chief executive at Equifax.
“It’s about sifting through the previously identified stolen data, analyzing other information in our databases that was not taken by the attackers, and making connections that enabled us to identify additional individuals.”
The US company still hasn’t notified the newly identified consumers because their social security numbers were not exposed in the hack, hackers only accessed their partial driver’s license information.
Equifax announced it would notify the newly identified consumers and will offer them identity theft protection and credit file monitoring services.
The company is now facing federal investigations as well as class-action lawsuits over the massive hack.
