Sitecore Security Snafu: Hackers Exploit Old ASP.NET Keys for RCE Mayhem!
Google warns that threat actors are exploiting an exposed ASP.NET machine key for remote code execution on vulnerable Sitecore deployments. Using a sample key from outdated Sitecore guides, hackers execute ViewState deserialization attacks. Sitecore has addressed the flaw, but the attackers already had a party with WeepSteel malware and a buffet of open-source tools.
Hot Take:
In a plot twist worthy of a cyber-thriller, a sample machine key meant for demonstration purposes has been repurposed by cybercriminals as their own skeleton key! Who knew 2017 could still haunt us more than our questionable fashion choices from that era? Google has sounded the alarm, and Sitecore is playing the hero with a timely advisory. Move over, ’90s hackers in trench coats, these digital mischief-makers are wielding ViewState deserialization like it’s the latest gadget from a spy movie.
Key Points:
- Cybercriminals exploit a sample ASP.NET machine key for RCE in Sitecore deployments.
- Vulnerable versions of Sitecore XM and XP prior to 9.0 are at risk.
- Google observes the use of WeepSteel malware for internal reconnaissance.
- Sitecore’s advisory provides mitigation guidance and IoCs.
- Attackers maintain persistence with compromised credentials and admin accounts.
