HDFC Bank Global Score (TPRM)XXXX

Description: Several Indian banks have taken drastic steps in response to a security breach that may have compromised up to 3.25 million debit cards—or 0.5% of the approximately 700 million debit cards that Indian banks have issued. The financial institution is Hitachi Payment Services, a subsidiary of Hitachi Ltd. that oversees ATM network processing for Yes Bank Ltd., according to banking industry insiders. After that, the State Bank of India quickly disabled a few clients' debit cards, and it was currently replacing those cards to stop fraud. The top three private sector lenders, ICICI Bank, HDFC Bank, and Axis Bank, each stated in separate announcements that there may have been card account breaches following usage at non-bank ATMs. Additionally, certain consumers' debit cards are being reissued by Standard Chartered's Indian division.
Description: In March 2023, HDFC Bank experienced a significant data breach, compromising the personal and financial information of 600,000 customers. The stolen data encompassed a wide range of sensitive details, including names, birthdates, contact numbers, email addresses, residential addresses, employment data, credit scores, and loan specifics. Following the data leak, numerous customers reported unauthorized transactions from their bank accounts and became targets of phishing attempts. The breach exposed customers to considerable financial risk and identity theft, raising concerns about the bank's cybersecurity measures and the protection of client information. This incident highlights the critical need for enhanced security protocols and vigilance in safeguarding customer data against the evolving tactics of cyber criminals.

Marshmallow is a lightweight library for converting complex objects to and from simple Python datatypes. In versions from 3.0.0rc1 to before 3.26.2 and from 4.0.0 to before 4.1.2, Schema.load(data, many=True) is vulnerable to denial of service attacks. A moderately sized request can consume a disproportionate amount of CPU time. This issue has been patched in version 3.26.2 and 4.1.2.
KEDA is a Kubernetes-based Event Driven Autoscaling component. Prior to versions 2.17.3 and 2.18.3, an Arbitrary File Read vulnerability has been identified in KEDA, potentially affecting any KEDA resource that uses TriggerAuthentication to configure HashiCorp Vault authentication. The vulnerability stems from an incorrect or insufficient path validation when loading the Service Account Token specified in spec.hashiCorpVault.credential.serviceAccount. An attacker with permissions to create or modify a TriggerAuthentication resource can exfiltrate the content of any file from the node's filesystem (where the KEDA pod resides) by directing the file's content to a server under their control, as part of the Vault authentication request. The potential impact includes the exfiltration of sensitive system information, such as secrets, keys, or the content of files like /etc/passwd. This issue has been patched in versions 2.17.3 and 2.18.3.
Fedify is a TypeScript library for building federated server apps powered by ActivityPub. Prior to versions 1.6.13, 1.7.14, 1.8.15, and 1.9.2, a Regular Expression Denial of Service (ReDoS) vulnerability exists in Fedify's document loader. The HTML parsing regex at packages/fedify/src/runtime/docloader.ts:259 contains nested quantifiers that cause catastrophic backtracking when processing maliciously crafted HTML responses. This issue has been patched in versions 1.6.13, 1.7.14, 1.8.15, and 1.9.2.
Authenticated Remote Code Execution (RCE) in PluXml CMS 5.8.22 allows an attacker with administrator panel access to inject a malicious PHP webshell into a theme file (e.g., home.php).
An issue was discovered in Xiongmai XM530 IP cameras on firmware V5.00.R02.000807D8.10010.346624.S.ONVIF 21.06. The GetStreamUri exposes RTSP URIs containing hardcoded credentials enabling direct unauthorized video stream access.
