Phishing gone: eBay patches to block session-jacking Magento holes

XSS, CRSF, and input holes fixed


Vulnerability Lab researcher Hadji Samir says eBay has squashed three vulnerabilities in its Magento shopping platform that could permit session hijacking and man-in-the-middle attacks.

The penetration tester disclosed this month the vulnerabilities along with proof-of-concept videos showing how attackers could steal session data and phish users.

Samir says the holes include a persistent input validation web vulnerabiility, a cross-site scripting (XSS) hole, and a cross-site request forgery (CSRF) bug.

"The [inject] vulnerability allows remote attackers to inject own script code to the application-side of the affected service module ... successful exploitation of the application-side vulnerability results in session hijacking, persistent phishing, persistent external redirects and persistent manipulation affected or connected module context," Samir says.

"Remote [XSS] attackers are able to inject own script codes to client-side application requests.

"The [CSRF] attacker can for example intercept the session to delete all existing messages."

Samir says the three vulnerabilities ranked as medium flaws attracting a security score averaging three.

He notes that the CSRF hole in phpbb was disclosed "some years ago".

Each was disclosed in March under the online tat bazaar's bug bounty program which paid out undisclosed monetary rewards and patched last month. ®

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality.

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

    Chinese cyberspies targeted two Russian defense institutes and possibly another research facility in Belarus, according to Check Point Research.

    The new campaign, dubbed Twisted Panda, is part of a larger, state-sponsored espionage operation that has been ongoing for several months, if not nearly a year, according to the security shop.

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.
