View CSAF 1. EXECUTIVE SUMMARY CVSS v4 9.3 ATTENTION: Exploitable remotely/low attack complexity Vendor: Hitachi Energy Equipment: Service Suite Vulnerabilities: Use of Less Trusted Source, Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling'), Integer Overflow or Wraparound, Out-of-bounds Write, Allocation of Resources Without Limits or Throttling, Exposure of Sensitive Information to an Unauthorized Actor, Memory Allocation with Excessive Size Value, Out-of-bounds Read, Uncontrolled Resource Consumption, Improper Resource Shutdown or Release, Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to compromise the confidentiality, integrity, or availability of affected devices. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Hitachi Energy reports the following products are affected: Service Suite: Versions 9.8.1.3 and prior 3.2 VULN...

Uncontrolled resource consumption in Windows Deployment Services allows an unauthorized attacker to deny service locally.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to invest time in repeated exploitation attempts through sending constant or intermittent data.

Improper input validation in Windows Hyper-V allows an unauthorized attacker to deny service locally.

Uncontrolled resource consumption in Remote Desktop Gateway Service allows an unauthorized attacker to deny service over a network.

Sensitive data storage in improperly locked memory in Remote Desktop Gateway Service allows an unauthorized attacker to deny service over a network.

Improper input validation in Active Directory Certificate Services (AD CS) allows an authorized attacker to deny service over a network.

Out-of-bounds read in Windows Transport Security Layer (TLS) allows an unauthorized attacker to deny service over a network.

A Denial of Service (DoS) vulnerability has been identified in the KnowledgeBaseWebReader class of the run-llama/llama_index project, affecting version ~ latest(v0.12.15). The vulnerability arises due to inappropriate secure coding measures, specifically the lack of proper implementation of the max_depth parameter in the get_article_urls function. This allows an attacker to exhaust Python's recursion limit through repeated function calls, leading to resource consumption and ultimately crashing the Python process.

## Summary `Rack::QueryParser` parses query strings and `application/x-www-form-urlencoded` bodies into Ruby data structures without imposing any limit on the number of parameters, allowing attackers to send requests with extremely large numbers of parameters. ## Details The vulnerability arises because `Rack::QueryParser` iterates over each `&`-separated key-value pair and adds it to a Hash without enforcing an upper bound on the total number of parameters. This allows an attacker to send a single request containing hundreds of thousands (or more) of parameters, which consumes excessive memory and CPU during parsing. ## Impact An attacker can trigger denial of service by sending specifically crafted HTTP requests, which can cause memory exhaustion or pin CPU resources, stalling or crashing the Rack server. This results in full service disruption until the affected worker is restarted. ## Mitigation - Update to a version of Rack that limits the number of parameters parsed, or - ...
