Wodify has some vulnerabilities which can be easily exploited by hackers according to a cybersecurity research firm. With the vulnerability, hackers are able to extract workout data, personal information as well as financial information from victims.
Wodify is a gym management web app that is used among CrossFit boxes in the US and other countries to help them grow. Currently, there are about 5,000 gyms for things like class scheduling and billing.
A senior consultant for Bishop Fox cybersecurity firm Dardan Prebreza made it known in a new report that a slate of vulnerabilities “allowed reading and modifying the workouts of all users of the Wodify platform.”
Through the attack, access “was not limited to a single gym/box/tenant, so it was possible to enumerate all entries globally and modify them,” Prebreza added, noting that an attacker could hijack a user’s session, steal a hashed password, or the user’s JWT through the Sensitive Information Disclosure vulnerability.
“Thus, a combination of these three vulnerabilities could have a severe business and reputational risk for Wodify, as it would allow an authenticated user to modify all their production data, but also extract sensitive PII,” Prebreza said.
“Additionally, compromising administrative gym user accounts could allow an attacker to modify the payment settings, and thus, have a direct financial impact, as the attacker could eventually get paid by the gym members instead of the legitimate gym owner(s). An authenticated attacker could read and modify all other users’ workouts data, extract PII, and eventually gain access to administrative accounts with the aim of financial gains.”
He rated the vulnerability risk level high because of the fact that it could lead to severe reputational damage and financial ramifications to Wodify gyms and boxes that could have their payment settings tampered with.
In his report, there were timelines of vulnerabilities discovered back in January 7th just before Wodify was contacted on February 12th. The company acknowledged the vulnerabilities on February 23rd but didn’t respond to further requests for information. Also attempts to get a comment from the firm by the media publisher failed.
Wodify CEO Ameet Shah was contacted and he connected the Bishop Fox team with Wodify’s head of technology, who held meetings with the company throughout April to address the issues.
Then back on April 19th, Wodify confirmed that the vulnerabilities would be fixed within 90 days but from there, there had been a push back on the patch date for the problems.
First, the company pledged to release a patch in May but they pushed it to June 11 before pushing it again to June 26. Wodify did not respond to Bishop Fox for another month, admitting that they were pushing the patch back to August 5.
After so many attempts to reach Wodify by Bishop Fox to no avail, the cybersecurity firm said they told Wodify that they’ll publicly disclose the vulnerabilities on August 6th but never did until Friday, August 13th.
Wodify has not confirmed if there is actually a patch yet, and Bishop Fox urged customers to get in touch with the company.
“The Wodify application was affected by insufficient authorization controls, allowing an authenticated attacker to disclose and modify any other user’s workout data on the Wodify platform,” Prebreza explained.
“The data modification example in the report was performed with consent on a collaborator’s account, and the proof-of-concept payload was removed following the screenshot. However, the ability to modify data means that an attacker could modify all workout results and insert malicious code to attack other Wodify users, including instance or gym administrators.”
The vulnerabilities according to the report ranged from insufficient authorization controls to sensitive information disclosure and stored cross-site scripting which can be leveraged in other attacks.
With that, an attacker would be able to change all of a Wodify user’s workout data such as profile pictures and names. An attacker can even insert malicious code that could go after other Wodify users such as gym administrators.
Erich Kron, security awareness advocate at KnowBe4, said this was an unfortunate case of an organization not taking a vulnerability disclosure seriously.
“While the initial thought of just wiping someone’s workout history may seem insignificant to many, the fact that an attacker can access the account and associated information, possibly including payment methods and personal information, is a real problem,” Kron said.
“Even just the workout information can be sensitive if the wrong person uses it to find patterns, for example the days and times a CEO for an organization typically works out, and uses it for malicious purposes. Organizations that create software should always have a process in place for dealing with reported vulnerabilities such as this, and must take them seriously.”
