In July, Secunia research issued 674 advisories for 83 unique vendors in 361 products and 475 unique versions, while issued 97 rejection notice advisories. An increase of 34.5% advisories from the previous month.
A Zero-day vulnerability was reported in Cisco ASA firewall and FDA products.
Oracle overtook RedHat as a top vendor with most vulnerabilities.
The amount of browsers vulnerabilities and their relevant patches are Achilles’ heel of effective patch management.
A vulnerability is reported in the web service system that allows remote access to Cisco ASA (Adaptive Security Appliance) – a network firewall and Cisco’s Firepower Threat Defence. An attacker can send a specially crafted HTTP request that can traverse the servers’ file system and also establish an SSL VPN or AnyConnect VPN session to the devices by impersonating another user. A lack of proper input validation causes it. There are reports of a publicly available exploit being used in targeted attacks.
Cisco ASA 9.6 till 9.14 are affected. Secunia Research has issued SA96432, which has further details.
Call to Action
- Cisco ASA running lower than 9.6 version should migrate to the latest supported software 126.96.36.199 or above.
- Versions from 9.6 till 9.14 needs to update to latest versions as described here.
- Cisco FDA 6.2.2 till 6.6.0 are affected and should be updated to the latest fixed released versions as mentioned on the above link.
- SUSE Linux = 58
- Amazon Linux = 49
- Ubuntu = 37
- Fedora = 35
- Oracle Linux = 34
- Red Hat Enterprise Linux = 28
- CentOS Advisories = 7
- Microsoft OS Advisories = 7

Advisories by Attack Vector.
65% of vulnerabilities can be exploited from remote, which makes the remediation efforts even more critical.
Advisories by Average CVSS Score
A CVSS score is a metric that is used to measure the severity of a vulnerability. CVSS3 specifications and the criteria details can be found at this link.
CVSS ranges from 0 to 10. 0 being the lowest and 10 being the highest score; the advisories spread is as below:
CVSS 3 Score
- Advisories with Low CVSS3 under 4.0: 39 (5.79%)
- Advisories with Mid CVSS3 range 4-7: 231 (34.27%)
- Advisories with High CVSS3 range 7-10: 404 (59.94%)
Advisories by Solution
An add-on by Software Vulnerability Research and Software Vulnerability Manager is Threat Intelligence. We give a score from 0 to 100 depending upon its severity, exploit availability, inclusion in penetration testing tools and the likelihood of being exploited. A detailed explanation of Threat Score calculation is available at this link.
- Advisories with positive Threat Score (1+): 405 (60.09%)
- None Threat Score SAIDs (=0): 269 (39.91%)
- Low-Range Threat Score SAIDs (1-12): 189 (28.04%)
- Medium-Range Threat Score SAIDs (13-23): 169 (25.07%)
- High-Range Threat Score SAIDs (24-44): 17 (2.52%)
- Critical-Range Threat Score SAIDs (45-70): 14 (2.08%)
- Very Critical Threat Score SAIDs (71-99): 16 (2.37%)
Ransomware, Malware, and Exploit Kits:
- Historically Linked to Ransomware: 10 (1.48%)
- Historically Linked to Malware: 79 (11.72%)
- Linked to a Recent Cyber Exploit: 86 (12.76%)
- Related to a Historical Cyber Exploits: 255 (37.83%)
- Included in Penetration Testing Tools: 275 (40.80%)
The amount of reported vulnerabilities is on the rise. Linux/Unix based OS are most vulnerable. Browers patches are released from 3 to 6 times a month which makes patching effort quite tricky especially for Google Chrome and Mozilla Firefox. Zero days must be prioritized as a likelihood of an attack is very high.
