CVSS v3.1 |
| A buffer overflow in the AMD Secure Processor (ASP) bootloader could allow an attacker to overwrite memory, potentially resulting in privilege escalation and arbitrary code execution. |
| Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution. |
| Insufficient input parameter sanitization in AMD Secure Processor (ASP) Boot Loader (legacy recovery mode only) could allow an attacker to write out-of-bounds to corrupt Secure DRAM potentially resulting in denial of service. |
| Improper access control in AMD Secure Encrypted Virtualization (SEV) firmware could allow a malicious hypervisor to bypass RMP protections, potentially resulting in a loss of SEV-SNP guest memory integrity. |
| Insufficient or Incomplete Data Removal in Hardware Component in SEV firmware doesn't fully flush IOMMU. This can potentially lead to a loss of confidentiality and integrity in guest memory. |
| Improper access control in secure encrypted virtualization (SEV) could allow a privileged attacker to write to the reverse map page (RMP) during secure nested paging (SNP) initialization, potentially resulting in a loss of guest memory confidentiality and integrity. |
| Memory corruption while processing MFC channel configuration during music playback. |
| Improper Input Validation vulnerability in qs (parse modules) allows HTTP DoS.This issue affects qs: < 6.14.1.
Summary
The arrayLimit option in qs did not enforce limits for bracket notation (a[]=1&a[]=2), only for indexed notation (a[0]=1). This is a consistency bug; arrayLimit should apply uniformly across all array notations.
Note: The default parameterLimit of 1000 effectively mitigates the DoS scenario originally described. With default options, bracket notation cannot produce arrays larger than parameterLimit regardless of arrayLimit, because each a[]=valueconsumes one parameter slot. The severity has been reduced accordingly.
Details
The arrayLimit option only checked limits for indexed notation (a[0]=1&a[1]=2) but did not enforce it for bracket notation (a[]=1&a[]=2).
Vulnerable code (lib/parse.js:159-162):
if (root === '[]' && options.parseArrays) {
obj = utils.combine([], leaf); // No arrayLimit check
}
Working code (lib/parse.js:175):
else if (index <= options.arrayLimit) { // Limit checked here
obj = [];
obj[index] = leaf;
}
The bracket notation handler at line 159 uses utils.combine([], leaf) without validating against options.arrayLimit, while indexed notation at line 175 checks index <= options.arrayLimit before creating arrays.
PoC
const qs = require('qs');
const result = qs.parse('a[]=1&a[]=2&a[]=3&a[]=4&a[]=5&a[]=6', { arrayLimit: 5 });
console.log(result.a.length); // Output: 6 (should be max 5)
Note on parameterLimit interaction: The original advisory's "DoS demonstration" claimed a length of 10,000, but parameterLimit (default: 1000) caps parsing to 1,000 parameters. With default options, the actual output is 1,000, not 10,000.
Impact
Consistency bug in arrayLimit enforcement. With default parameterLimit, the practical DoS risk is negligible since parameterLimit already caps the total number of parsed parameters (and thus array elements from bracket notation). The risk increases only when parameterLimit is explicitly set to a very high value. |
| A use after free in the SEV firmware could allow a malicous hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent potentially resulting in loss of integrity. |
| Improper handling of error condition during host-induced faults can allow a local high-privileged attack to selectively drop guest DMA writes, potentially resulting in a loss of SEV-SNP guest memory integrity |
| Improper handling of overlap between the segmented reverse map table (RMP) and system management mode (SMM) memory could allow a privileged attacker corrupt or partially infer SMM memory resulting in loss of integrity or confidentiality. |
| An issue inTcpreplay v4.5.1 allows a local attacker to cause a denial of service via a crafted file to the tcpedit_dlt_getplugin function at src/tcpedit/plugins/dlt_utils.c. |
| Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution. |
| A Time-of-check time-of-use (TOCTOU) race condition in the SMM communications buffer could allow a privileged attacker to bypass input validation and perform an out of bounds read or write, potentially resulting in loss of confidentiality, integrity, or availability. |
| Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity. |
| Improper input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest data integrity. |
| Improper syscall input validation in ASP (AMD Secure Processor) may force the kernel into reading syscall parameter values from its own memory space allowing an attacker to infer the contents of the kernel memory leading to potential information disclosure. |
| An AXIS Camera Station Pro feature can be exploited in a way that allows a non-admin user to view information they are not permitted to. |
| An out-of-band SQL injection vulnerability (OOB SQLi) has been detected in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. Exploiting this vulnerability in the parameter 'Id_usuario' and 'Id_evaluacion’ in ‘/evaluacion_competencias_evalua_old.aspx’, could allow an attacker to extract sensitive information from the database through external channels, without the affected application returning the data directly, compromising the confidentiality of the stored information. |
| Information disclosure when UE receives the RTP packet from the network, while decoding and reassembling the fragments from RTP packet. |
