Also notable this month is the dramatic growth in CVE-2020-25078, which is also an IoT vulnerability but this time in several IP cameras. On the one hand the volume of traffic scanning for this vulnerability was not remarkable, with ~3600 connections in February, but only 200 connections were attempted in January, which means traffic increased…
Read MoreHere we are in April 2023, which gives us another opportunity to see what vulnerabilities attackers were most interested in last month. After receiving a huge amount of attacker attention from November 2022 to February 2023, CVE-2020-8958 has returned to volumes of traffic more consistent with what we’d come to expect over the last year…
Read MoreThe stubborn one-way passage of time means that it is time for another round of vulnerability targeting intelligence. Web attacks in May 2023 had a lot in common with those in April, with eight of the top ten vulnerabilities remaining consistent across the two months. In that vein of continuity, CVE-2020-8958, the Guangzhou GPON router…
Read MoreThe most glaring example of a predominant vulnerability type is visible in the top row, which is CWE-79: Improper Neutralization of Input During Web Page Generation, more commonly known as cross-site scripting (XSS). Cross-site scripting dominated the field of CVEs from 2011-2016, at times making up 60% of published vulns in a quarter. SQL injection…
Read MoreConclusions This month we were able to add seven newly observed CVEs to our list of confirmed exploited vulnerabilities: CVE-2012-4940, a directory traversal vulnerability in the Axigen Free Mail Server. CVE-2016-4945, a cross-site scripting flaw in Citrix Netscaler Gateway CVE-2017-11511 and CVE-2017-11512, arbitrary file download flaws at different URIs in the Zoho ManageEngine ServiceDesk tool…
Read MoreWelcome back to the Sensor Intelligence Series, our recurring monthly summary of vulnerability intelligence based on distributed passive sensor data. We’ll start off this month’s analysis with a look at some activity from the August dataset, which demonstrates some of the oddities we occasionally see, and then dig into the changes we saw in September…
Read MoreOverall Scanning Traffic Changes Lest the downward trend shown in Figure 2 makes it seem like overall scanning traffic may be abating, it’s important to note that the volume of scanning we observed has remained relatively constant, at least over the last three months, increasing by approximately 5.1% from August to September, then falling approximately…
Read MoreCommon Non-CVE Traffic It may be easy to conclude from the above figures that even though overall traffic has held steady, CVE exploitation attempts, at least for the CVEs and vulnerabilities we track, has decreased. That’s true, but there is a great deal of traffic that our sensor network sees that is not reflected in…
Read MoreZooming Out to Look at 2023 One of the questions we frequently get asked about this data is about attribution, that is, who is doing the scanning. This is a difficult question, because it is quite well understood that many threat actors take great pains to do at least a bit of obfuscation of their…
Read MoreThis view is also notable since it is the first time we’re seeing any of these newly added, high-profile CVEs show up. Second row, far right is CVE-2014-6271, an OS command injection vulnerability more commonly known as Shellshock/Bashdoor. Shellshock shows more targeting variability from month to month than most CVEs (not including CVE-2020-11625, which has…
