A Switzerland-based penetration testing firm, High-Tech Bridge, revealed that vulnerabilities in NASDAQ's website were left unpatched for weeks.

IIia Kolochenko, CEO at High-Tech Bridge, told the NY Daily News on Monday that he discovered the flaws on the stock exchange's website “in just 10 minutes with a Firefox browser without any special tools or software”.

The bugs could have allowed an attacker to carry out cross-site scripting (XSS) attacks, meaning a hacker could inject HTML code into a site to steal visitors' data, such as cookies, or manipulate what they see, the outlet reported.

The issue has since been fixed by NASDAQ as of Monday, according to reports, but long after Kolochenko notified the stock exchange of the issue on 2nd September.

In a statement emailed to SCMagazine.com on Tuesday, NASDAQ said that it responded “immediately” to High-Tech Bridge's warnings.

“We take all information security matters seriously,” the statement said. “We work with leading security vendors and have a trained and professional team that evaluates all credible threats across our digital assets.”

UPDATE: In an email received onTuesday, Kolochenko told SCMagazine.com that he reported two vulnerabilities to NASDAQ, but that he "didn't want to dig further without their permission".

"I think that if somebody perform[ed] a more profound testing, he [could] find much more vulnerabilities, and probably even more dangerous ones than XSS," he wrote. Kolochenko added that NASDAQ moved to address the issue when it got word of the issue being publicised.
