The two vulnerabilities have been addressed in the foll...

The maintainers of the open-source continuous integration/continuous delivery and deployment (CI/CD) automation software Jenkins have resolved nine security flaws, including a critical bug that, if successfully exploited, could result in remote code execution (RCE). The issue, assigned the CVE identifier  CVE-2024-23897 , has been described as an arbitrary file read vulnerability through the built-in command line interface ( CLI ) "Jenkins uses the args4j library to parse command arguments and options on the Jenkins controller when processing CLI commands," the maintainers  said  in a Wednesday advisory. "This command parser has a feature that replaces an @ character followed by a file path in an argument with the file's contents (expandAtFiles). This feature is enabled by default and Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable it." A threat actor could exploit this quirk to read arbitrary files on the Jenkins controller file system...

A security flaw has been disclosed in Kyocera’s  Device Manager  product that could be exploited by bad actors to carry out malicious activities on affected systems. "This vulnerability allows attackers to coerce authentication attempts to their own resources, such as a malicious SMB share, to capture or relay Active Directory hashed credentials if the ‘Restrict NTLM: Outgoing NTLM traffic to remote servers’ security policy is not enabled," Trustwave  said . Tracked as  CVE-2023-50916 , Kyocera, in an  advisory  released late last month, described it as a path traversal issue that enables an attacker to intercept and alter a local path pointing to the backup location of the database to a universal naming convention (UNC) path. This, in turn, causes the web application to attempt to authenticate the rogue UNC path, resulting in unauthorized access to clients’ accounts and data theft. Furthermore, depending on the configuration of the environment, it cou...

A zero-day flaw in the Zimbra Collaboration email software was exploited by four different groups in real-world attacks to pilfer email data, user credentials, and authentication tokens. "Most of this activity occurred after the initial fix became public on GitHub," Google Threat Analysis Group (TAG)  said  in a report shared with The Hacker News. The flaw, tracked as  CVE-2023-37580  (CVSS score: 6.1), is a  reflected cross-site scripting  (XSS) vulnerability impacting versions before 8.8.15 Patch 41. It was  addressed  by Zimbra as part of patches released on July 25, 2023. Successful exploitation of the shortcoming could allow execution of malicious scripts on the victims' web browser simply by tricking them into clicking on a specially crafted URL, effectively initiating the XSS request to Zimbra and reflecting the attack back to the user. Google TAG, whose researcher Clément Lecigne was credited with discovering and reporting the bug, s...

The threat actor known as  Winter Vivern  has been observed exploiting a zero-day flaw in Roundcube webmail software on October 11, 2023, to harvest email messages from victims' accounts. "Winter Vivern has stepped up its operations by using a zero-day vulnerability in Roundcube," ESET security researcher Matthieu Faou  said  in a new report published today. Previously, it was using known vulnerabilities in Roundcube and Zimbra, for which proofs-of-concept are available online." Winter Vivern, also known as TA473 and UAC-0114, is an  adversarial collective  whose objectives align with that of Belarus and Russia. Over the past few months, it has been attributed to attacks against Ukraine and Poland, as well as government entities across Europe and India. The group is also assessed to have exploited another flaw Roundcube as recently as August and September (CVE-2020-35730), making it the  second nation-state group after APT28  to target the op...

More details have emerged about a set of now-patched cross-site scripting (XSS) flaws in the  Microsoft Azure HDInsight  open-source analytics service that could be weaponized by a threat actor to carry out malicious activities. "The identified vulnerabilities consisted of six stored XSS and two reflected XSS vulnerabilities, each of which could be exploited to perform unauthorized actions, varying from data access to session hijacking and delivering malicious payloads," Orca security researcher Lidor Ben Shitrit  said  in a report shared with The Hacker News. The issues were addressed by Microsoft as part of its  Patch Tuesday updates  for August 2023. The disclosure comes three months after similar shortcomings were reported in the  Azure Bastion and Azure Container Registry  that could have been exploited for unauthorized data access and modifications. The list of flaws is as follows - CVE-2023-35393  (CVSS score: 4.5) - Azure Apac...

Two "dangerous" security vulnerabilities have been disclosed in Microsoft Azure Bastion and Azure Container Registry that could have been exploited to carry out cross-site scripting (XSS) attacks. "The vulnerabilities allowed unauthorized access to the victim's session within the compromised Azure service iframe, which can lead to severe consequences, including unauthorized data access, unauthorized modifications, and disruption of the Azure services iframes," Orca security researcher Lidor Ben Shitrit  said  in a report shared with The Hacker News. XSS attacks  take place when threat actors inject arbitrary code into an otherwise trusted website, which then gets executed every time when unsuspecting users visit the site. The two flaws identified by Orca leverage a weakness in the postMessage iframe, which enables cross-origin communication between Window objects. This meant that the shortcoming could be abused to embed endpoints within remote servers usin...

A pair of severe security vulnerabilities have been disclosed in the Jenkins open source automation server that could lead to code execution on targeted systems. The flaws, tracked as  CVE-2023-27898  and  CVE-2023-27905 , impact the Jenkins server and Update Center, and have been collectively christened  CorePlague  by cloud security firm Aqua. All versions of Jenkins versions prior to 2.319.2 are vulnerable and exploitable. "Exploiting these vulnerabilities could allow an unauthenticated attacker to execute arbitrary code on the victim's Jenkins server, potentially leading to a complete compromise of the Jenkins server," the company said in a report shared with The Hacker News. The shortcomings are the result of how Jenkins processes plugins available from the  Update Center , thereby potentially enabling a threat actor to upload a plugin with a malicious payload and trigger a cross-site scripting (XSS) attack. "Once the victim opens the ' Availabl...

Update (22 June 2019)  — More technical details and proof-of-concept for the OutLook for Android vulnerability has been released that we have covered in a separate article here. Microsoft today released an updated version of its "Outlook for Android" that patches an important security vulnerability in the popular email app that is currently being used over 100 million users. According to an advisory , Outlook app with versions before 3.0.88 for Android contains a stored cross-site scripting vulnerability ( CVE-2019-1105 ) in the way the app parses incoming email messages. If exploited, remote attackers can execute malicious in-app client-side code on the targeted devices just by sending them emails with a specially crafted message. "The attacker who successfully exploited this vulnerability could then perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user." According to Microsoft, the fl...

Scammers have again targeted more than one billion active users of the popular social networking giant Facebook, to infect as many victims as possible. Not by serving fake post, neither by providing malicious video link, instead this time scammers have used a new way of tricking Facebook users into injecting or placing malicious JavaScript or client-side code into their web browsers. This malicious code could allow an attacker to gain access to victims’ accounts, thereby using it for fraud, to send spams, and promoting further attacks by posting the scam on timeline to victims’ friends. This technique is known as Self Cross-site Scripting or Self XSS. Self-XSS (Self Cross-Site Scripting) scam is a combination of social engineering and a browser vulnerability , basically designed to trick Facebook users’ into providing access to their account. Once an attacker or scammer gets access to users’ Facebook account, they can even post and comment on things on users’ behalf. ...
