OtherFortinet Patches Critical Authentication Bypass in FortiWeb Allowing Login with Random Credentials
Fortinet has released security updates addressing multiple vulnerabilities across FortiWeb, FortiManager, and FortiClient products. The most severe issue, tracked as CVE-2026-26035, affects FortiWeb and carries a CVSS score of 8.8. The flaw occurs when administrative accounts configured with remote RADIUS authentication use the wildcard option, which is disabled by default. Under these conditions, an unauthenticated remote attacker can gain administrative access to the web application firewall by supplying arbitrary usernames and passwords. Successful exploitation grants full control over the FortiWeb instance, potentially compromising web application security. The vulnerability impacts FortiWeb versions 8.0, 7.6, 7.4, 7.2, and 7.0, with fixes available in versions 8.0.3, 7.6.7, 7.4.12, and 7.2.13. No active exploitation of the authentication bypass flaws has been observed so far, but the risk of remote administrative access makes immediate patching essential for exposed appliances.
CISA Adds Exploited Flaws in FortiOS and VeloCloud Orchestrator to Known Exploited Vulnerabilities Catalog
The US Cybersecurity and Infrastructure Security Agency has added two actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog. CVE-2026-16812 affects the on-premises version of Arista VeloCloud Orchestrator and allows OS command injection that can lead to data leakage, tampering, and denial of service. The flaw carries a maximum CVSS v3.1 base score of 10.0 and is rated Critical. CVE-2025-68686 impacts Fortinet FortiOS and can be used to bypass specific patches and steal sensitive information when combined with another vulnerability that grants prior filesystem access. Federal agencies must remediate the VeloCloud issue by July 30 and the FortiOS issue by August 10.
Why Deep Packet Inspection Overestimates Its Reach in Encrypted Networks
Modern encryption has fundamentally limited the effectiveness of Deep Packet Inspection systems, leaving network monitors with only metadata and behavioral patterns rather than actual content. DPI tools can still classify traffic types and apply policies based on visible flow characteristics, but they cannot read messages, files, or credentials inside properly encrypted sessions without explicit TLS inspection. The article details how TLS 1.3, Encrypted Client Hello, and QUIC further reduce passive visibility while corporate inspection remains possible only when endpoint devices trust an organizational certificate. Russian regulatory requirements around TSPU systems are discussed separately from corporate DPI use, with emphasis on the need for technical confirmation rather than assumptions. The piece also clarifies distinctions between DPI, IDS, IPS, and DLP, and explains why machine learning cannot convert metadata into decrypted payloads. Overall, the analysis shows that DPI remains useful for traffic management and known-threat detection where visibility exists, but it cannot serve as a complete security foundation.
CISA Adds Three Exploited Vulnerabilities in FortiSandbox and SharePoint to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog on July 16, 2026. Two of the flaws affect Fortinet’s FortiSandbox malware analysis product and involve OS command injection issues that can be triggered via specially crafted HTTP requests without requiring authentication. The third vulnerability impacts Microsoft SharePoint and stems from unsafe deserialization of untrusted data, potentially allowing remote code execution over the network. CISA’s action follows public advisories released by the vendors in April and June 2026. The agency is urging organizations to apply available patches and mitigations immediately to reduce the risk of compromise.
