Enhancing information security
Release Date:Aug 30, 2018
IT Security Center
The vulnerability countermeasure information database JVN iPedia (https://jvndb.jvn.jp/en/) is endeavoring to become a comprehensive vulnerability database where vulnerability information is aggregated for easy access for IT users. JVN iPedia collects and/or translates the vulnerability information published by 1) domestic software developers, 2) JVN (*1), a vulnerability information portal run by JPCERT/CC and IPA, and 3) NVD (*2), a vulnerability database run by NIST (*3). JVN iPedia has been making vulnerability information available to the public since April 25, 2007.
~ JVN iPedia now stores 85,280 vulnerabilities ~
The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 2nd quarter of 2018 (April 1 to June 30, 2018) is shown in the table below. As of the end of June 2018, the total number of vulnerabilities stored in JVN iPedia is 85,280 (Table 1-1, Figure 1-1).
As for the English version, the total of 1,922 vulnerabilities are available as shown in the lower half of the table.

Figure 2-1 shows the number of vulnerabilities newly added to JVN iPedia during the 2nd quarter of 2018, sorted by the CWE vulnerability types.
The type of the vulnerabilities reported most in the 2nd quarter is CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) with 514 cases, followed by CWE-79 (Cross-Site Scripting) with 422, CWE-200 (Information Exposure) with 373, CWE-20 (Improper Input Validation) with 365, CWE-264 (Permissions, Privileges, and Access Controls) with 276. CWE-119, the most reported vulnerability type this quarter, could allow attackers to execute malicious code on the affected servers and PCs, resulting in undesired consequences such as unauthorized access to and modification of data.
Software developers need to make sure to implement necessary security controls from the planning and design phase of software development to mitigate vulnerability. IPA provides tools and guidelines, such as "How to Secure Your Website" (*4), "Secure Programing Guide" (*5) and "AppGoat" (*6), a hands-on venerability learning tool, for website developers and operators to build secure websites.
Figure 2-2 shows the yearly change in the CVSSv2 rating scale based severity of vulnerabilities registered to JVN iPedia.
As for the vulnerabilities added to JVN iPedia in 2018, 30.0 percent are "level III" (7.0 - 10.0), 58.7 percent are "level ll" (4.0 – 6.9) and 11.3 percent are "level I" (0.0 – 3.9). This means 88.7 percent of all vulnerabilities registered are level II or higher, which are potentially critical enough to cause damage like information exposure or data modification.
Figure 2-3 shows the yearly change in the CVSSv3 rating scale based severity of vulnerabilities registered to JVN iPedia.
As for the vulnerabilities added to JVN iPedia in 2018, 18.4 percent are "Critical" (9.0 – 10.0), 43.5 percent are "High" (7.0 – 8.9), 36.8 percent are "Medium" (4.0 – 6.9) and 1.3 percent are "Low" (0.1 – 3.9).
To mitigate threats imposed by the known vulnerabilities, IT users should pay close attention to vulnerability information and update software they are using to a fixed version or apply a security patch as soon as possible when they become available. IT users can also check vulnerabilities newly published on JVN iPedia in RSS and XML format (*7) as well.
Figure 2-4 shows the yearly change in the type of software reported with vulnerability. Application vulnerabilities have been published most, accounting for 73.7 percent (5,065 out of 6,870) of the 2018 total.
Figure 2-5 shows the yearly change in the number of JVN iPedia-stored vulnerabilities in industrial control systems (ICS) used in critical infrastructure sectors. As of June 2018, the total of 1,460 ICS vulnerabilities have been registered.
Table 2-1 lists the top 20 software whose vulnerabilities were most registered to JVN iPedia during the 2nd quarter (April to June) of 2018.
In this quarter, many Android-related vulnerabilities were published. Ranked 1st is Qualcomm processor firmware with 268 vulnerabilities (firmware for all Qualcomm processors including SD and MSM is collectively treated as Qualcomm processor firmware) and ranked 2nd is Android OS with 207 vulnerabilities. The the 3rd and below are mostly OS products and many vulnerabilities in popular products, such as Microsoft's and Apple's, had been registered.
Besides those in the top 20 list, JVN iPedia stores and offers vulnerability information about a variety of software. IPA hopes software developers and users will make good use of JVN iPedia to efficiently check vulnerability information and take necessary action in a timely manner (*8).
